VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 34/35 sidemount thread type ?

hi there,
I have finally had my 34 /35 Chev standard re-upholstered and it was worth the wait of 13 months for the right man to do the job.
Pictures will follow in due course...
I am now looking for a wing nut to retain the side mount tire.
Does any one know the size and thread type used? The thread looks like a very fine one like UNF or similar. Maybe I could make one if I knew how to identify the thread, as in, weld some metal onto a nut and paint it.
cheers

My guess the thread is 1/2 X 20. That is what it is on mou 31. Without looking I believe the Filling Station has a T Nut that will work. You can hold a scale on the threads and count how many there are in one inch.

hi there,
thank you for your advise, but after doing a long search of the filling station, I could not find anything?
Peter

Most likely the thread is 1/2" fine thread, fine thread is easily visually identified from coarse thread. I assume your talking about SIDE MOUNT HARDWARE. Or are you talking about the rear mount. I cannot see either in your picture avatar

If you have a tap and die set, usually in a better set is a foldout tool that allows you to match the threads and identify them. It has all the thread counts on the various flip outs.

You could also place a 1/2 inch fine die over the end and carefully test the threads. I bought a couple of original side mount T nuts clamps for the top of the rod and ran a tap down them ato clean them up inside. I believe they were each fine thread 1/2". They were the closed top design.
now i have to find them.

That company in australia who makes a lot of brass and stainless chevrolet parts makes those sidemount T clamps.

Check out part number GR-256 on the Filling Station's web site. The sidemount "T" handle shown is for 1932 and 1933, but apparently it is a replacement for 1934 thru 1936 as well.

Last time i checked, I & I also was the supplier of these, but they are or were out of stock , with no time line on new stock coming in.

Thats why i bought used ones off ebay when they appeared, that was 6 months ago and i have not seen any more since.

LOOKED IT UP AND HERE IS THE LINK TO THE AUZZIE SITE VINTAGE AND CLASSIC REPRODUCTIONS

part number is CHE-094 sidemounted tee handle in stainlesss

Hi there all,
thank you all for your helpful and interesting replies to my questions.
I have a spare side-mount hardware rod , identical to the good one on the car.
I will take it into the local nut and bolt place and get them to positively identify the thread type.
They use a set of small gauges that was mentioned in a post. then they will try a nut on it to see if it is correct.

I checked my Chev box of old parts removed, and found a nut that fitted that was on a spring shackle pin. I replaced them all many years ago but never throw anything away that might be useful some day!
The Australian site for parts indeed has a SS T-nut fitting, a bit cheaper than the FS and postage would be cheaper too. I wont make any decisions until the thread is identified..
thank you all for you help

regards
Peter

I believe your sidemount clamp nut is a large looking nut. Not a T handle unless that is what you want to use. I'm looking for a driver side brace that goes from the up/Dn bolt into the cowl. If I knew how to attach a photo, I would

Quit all the guessing and tears..........Checker Auto.O'reillys auto here ...must have something in your ares has boxesof wingnuts or toggles they have the fine thread that fits. take your rod in and screw til you find the right size. worked for me

The 1934 1935 chevrolets pass cars and trucks for the sidemount hardware used a cast T handle. Some used whats called an open top t handle and some used the closed top design.

Before I acquired the pair of closed top ones I found a coupe trunk lid T handle, took the guts out and slipped it over the side rod to hold the tire clamp down, used a stainless washer on the top and finished it off with a stainless threaded acorn style nut. Its still on there even tho i have the other correct type. Problably cost $40--50--60 to plate and refinsh one of them.

mike...........

if you send me your email address I will forward you some pictures.

29-39 Master Parts Manual

7.646 P/N 366977 Handle-Clamp 29-33 all
P/N 376761 Nut-Clamp 34/35 DC,EC
7.629 P/N 376764 Clamp 34/5 DC,EC

Clamp is different because it has a larger hole. The T handle is not correct for 34-5 Standard.

I don't care if the t handle is wrong, it looks better than a nut on top.

"The 1934 1935 chevrolets pass cars and trucks for the sidemount hardware used a cast T handle. Some used whats called an open top t handle and some used the closed top design."

Mike, this statement is incorrect. It's ok to offer your opinion if you state as much, but if the poster buys the T handles thinking they are correct and will work for 34/5 std, he will have to drill out and re-tap the hole. The threaded diameter on the 34/5 long vertical bolt that mounts into the fender well is 9/16 with 18 threads per inch.

If the poster decides to do this at least it will be his decision and he will be informed.

Hi there,
what 35Pete says is true.
I took my spare hold down rod into the local nut and bolt place
for identification.
A 9/16 unf , 18 threads per inch nut fitted perfectly, so that's what it is.
I am now confused as to what the suppliers of the said handle actually have? they don't identify the threads types and pitch?

===================================================

What i described using a trunk lid handle from some car was done for my 35 std coupe which i used a nos left front welled fender i had nothing to go by for the sidemount hardware so i created my own using 1/2" aluminum rod threaded for 1/2" fine at bottom and same for the top. I made an aluminum plate for the fender where rod goes thru, put a chromed tire clamp from a pre 35 chevy on the fake spare tire. I used 7/8" round aluminum tube with 9/16" interior hole. Welded a short piece to the 7/8" tube at an angle and ran a long bolt thru the center of the fake tire to hold it in place.

The fake tire was made from 5 pieces of 1" thick pink extruded styrofoam in 24" cirles to amke a 5" wide tire. And glued together using pl3000 glue. I had a full surround tire cover made from black convertible top material to cover the fake spare.

nobody has said anything about the hardware i made or the fact the fake tire is about 4-5" too short.

I now own the correct left side mount hardware that i got when i bought the 35 standard roadster back in 2012. I will put my welled fender on that car when time comes and use all the right side mount stuff....except that bolt on top, its going to have a T handle , drilled and tapped out to 9/16 F.

Because chevrolet was too cheap to make a proper T handle for 34-35 doesn't mean i cannot have one.

mike

DOG.............thats what i always thought too. but apparently i am wrong, supposed to be a 9/16 F nut.

I and I catalogue also says up to 35 also for T handle ??
NOPE, on page 68 of I&I cat under hardware kit it shows 29---32 side mount hardware kit SM02S

then below that it shows 1929---1936 ***TRUCK SIDE MOUNT**** HARDWARE KIT SM02S and its the same item .

mike.............

Hi there Mike,
your are truly using " the mother of invention" to its limit. I have never failed to admire you determination to succeed at what every you try!
So you spare tire secret is now out.... and now you have the correct parts to put things right, well done. BTW are there any more fake secrets lurking in the wings? Marzipan tires, sugar coated spokes, chocolate sponge carpets?

regards
Peter

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Peter, yes i have a few more surprises lurking.

The fake spare tire at 24" tall really suits the cleaner less imposing look of the overly large real spare in a fender. Kinda overpowers the look of the car the stock size.

How about no upholstery inside the passenger area or the rumble seat area. Why ??????? , because i spent so much time doing the wood , also using dutch epifanes varnish at $50 a liter and selecting pieces that had a lot of character too the wood that it would be a shame to cover it up.

The seat back in the insert area i used cherry wood with a tremendous amount of distortion & colours. Its not a piece of wood they would normally use for furniture or kitchesn cabinets. I will just use lawn chair cushions and tie them on and remove when at a show. you stick your head inside this car, 1935 chevrolet roadster...SHAZZBOTT.......and your going to say, they used a whole tree to make this one.!!!!!


mike

Hi Mike,

we all keep our old cars in good fettle and do whatever is necessary for the moment.
Your car is magnificent in all regards.

Hey Mike... Do you hit a regular weekly cruise night in the summer? Some day I'm going to have to check out your rides...

I usually attend the " shake rabble roll diner " in whitby on Saturday nites and Monday nites.

went out to the one in Burlington Oakville a few years ago, that was in a mall south of QEW, should make a return visit. But with the rush hour traffic makes it a real pain to get to.

Shazzbott is just a collection of cowl, doors, quarter panels that have been envirotech stripped to bare metal. Wood parts are mostly refinished in special dutch varnish. Doors and rear gas tank cover panel are at Fawcett motor carriage co , here in whitby being redone.
