What is the correct angle to mount your rear in a 1930 chevy 3 window coupe

Hi AD30coupe,

Normally, around 3 and 3/4 inches or 43 degrees.

You gotta help us with a better description of the problem. ???????????

Depending upon various factors such as the level of the floor, tire inflation and etc., the angle of the 1930 Chevrolet torque tube is approximately 5 degrees.

5 degrees or 43 degrees? Raymundo where was the 43 degrees measured from, surely not from floor level? or was that supposed to be 4.3 degrees?

im putting a 55 chevy rear in and just wanted to make sure of the right degrees to set it in at. Thanks again for all your help everyone

Hi AD30coupe,

Please take my post further up this thread as a 'tongue in cheek' type remark.

When you go non stock, I'm out of here.

try and mount the diff so the pinion is at the same angle as the trans output shaft , or within 1 - 2 degrees of it .

Expect some flack from the restorers here when you reveal you are modifying an old chevy.

I myself wondered about that asking about degrees... Don't we usually just get everything stock and bolt it all together???? I don't even have a protractor in the shop, wonder if Harbor Freight has one?

A protractor level is a good tool to have around in the shop, and it can solve several problems for restorers, both mechanical and when installing new wood in the body. The protractor level is particularly useful when someone is installing a rebuilt '32 engine back into their '32 frame and the front motor mount is mistakenly put on top of the cross member instead of underneath where it belongs. :eek: :eek: :eek:

I had the wrong angle on the '69 SS Camaro (396) my son and I restored and after losing 2 drive shafts while driving we got a protractor and checked the angle and fixed it. No problems since then.

Don't go by what was there, check it after doing the restoration, like in my case the car had a 350 replacement motor and redoing the car with the 396 (402) changed the way the car sat and the angle. And if you use used parts (like the rear axle) it can have the wrong mounts and you can get a surprise like we did; and that is one surprise I don't EVER want to have again.

Yep when you mix engines trannys and differentials some funny things happen. I have a hard enough time making what appears to be stock work like I just removed what I believed to be a 1951 & 1952 Master Cylinder from a 51 parts car and it at first appeared to be stock till I got it out, it didn't have the rectangular lid that bolts on with 4 machine screws, It didn't have a lid it was cast without a lid, it had a larger filler plug about twice the Delco model and no brand name just some numbers stamped in. I don't have a clue what it is or where it came from, Then I noticed the link that connects the clutch peddle to the "L" shaped clutch rod, it should have been 6 1/8" long, it was 5 1/8" long and I had to unbolt the peddle completely in order to get the "L" link off. You just never know what you will run into with a 55 year old car. I probably will need both a protractor, a compass and a crow bar to get everything back together!

This is the proper method to check the angle of the rear end.

What do you suppose he is doing there? Getting ready to weld up a leak in the fuel line where it meets the tank? That would be a good idea, too.....

Looks safe enough to me-at least he blocked the wheels

Yes, that is right Chev Nut, he doesn't want the truck to roll away, he wants it to come straight down on his pumpkin head.

Note his posture, bent this way he will only be able to see if his shoes are tied (if he lives) the rest of his life...

silver linning = he could find a lot of lost change.

It would really be interesting to hear him explain why he decided this was a good idea.

Right Gator, I was noticing his posture, too. It made my hands sweat........

That is wild!! I'm sitting here cracking up so much I can't even call my brother-in-law who's visiting to come take a look. Unbelievable!! I see he used two pieces of wood to prop the truck up instead of just one. Do you think that was because of a previous bad experience. Can just hear him muttering, "Yep, I'll use two boards next time after I get outta hospital."

Eastwood sells an upscale version of this called " New Car Tilter "....See page 40 of their September 2004 catalog.

Yep Ray, that looks about like a 43 degree angle to me....

Oh, dear God! this reminds me of my youngest son's first attempts at being a mechanic. Would you believe he learned the basics of his present MOS as a Abrams Tank commander working on his first cars?

I wonder if this is a new way of stealing gas from a truck with a locking gas cap?

The original caption that came with this photo read: "Why women are smarter than men"! :eek: :eek: :eek:

Kinda makes you wonder what he was thinking?( I think the problem is he didn't think) OSHA's nightmare list. Do not attempt this at home, he is a trained professional. How the heck did he manage to get it to that angle in the first place, and how do you get it down?? Just knock out the boards???

There has to be "the rest of this story..." somewhere.
