have a 1940 Special deluxe with leaking vacuum shift assist. Looking for the linkage kit that will convert to standard non vacuum assist. Tried Chevys of the 40s, they are out. Any information would be greatly appraciated. Sincerely, John johnseabee@aol.com
I strongly urge you to repair the original vacuum shift. When working correctly it is a pleasure to drive. If you need help in the restoration of the shifting, come on back here and you will get good and correct advise.
I have 2 sets of linkage. One has been sandblasted and has a coat of POR 15 on it the other needs to be sandblasted and painted. Let me know if you are interested. I sold Ray (above poster) the parts to rebuild a vacuum assist, maybe he would give you a price on a rebuilt one, or fixing yours?
I don't have vacuum assist on my 41 so know the headache it is to get them adjusted right, but I kind of like the extra work it is to shift. Makes the car seem kind of less modern. It performs a lot like me at age 72, well worn, and a little ...!!!
Seems that your mind is made up to convert it to non-vacuum assist. I'm with Ray on this one and strongly encourage you to not do so.
You say there is vacuum leakage. Where is this occurring? Cylinder valve or tank?
What do you need to keep the vacuum shift? I may be able to help.
Let me know.
Best.

BTW: Adjustment is a piece o'cake when you have the adjusting tool. You can get one real cheap from FS or CotF. Just use to test after screwing the adjuster in or out. When you have it right take the tool out and then fix it in place so it doesn't turn when the unit.
BTW2: You may borrow the tool from someone. After use just don't return it and save the cost of buying one.
I replaced mine with the shift rod, maybe I didn't adjust it properly, it was hard to shift. Then I drove a friends 1940 chevy with the vacuum that was properly adjusted, piece of cake to shift. If I had to do it over, I would stay with the vacuum shifter. (I no longer own that car).

i' ll try again. If you can I would definitely keep your vacume shift. I have a 41 with it and it shifts great. I'm sure you can fix what you have or find a used one . I have a 53 without it and it shifts great too, but not with the vacume assist. Bottom line.. keep what you got ,you won't regret it.

If you are fortunate enough to have the vacuum assist canister to begin with. Mine was missing from the car when I got it. A field rescue '46 coupe.
Thank you for your helpful response, Since I could not find the manual shift linkage I decided to try and rescue the vacuum assist. I found to boot, new hoses and clamps, adjustment tool. Correct weight of oil to clean and lube container / leather seal (already completed that task as per instructions 1940 shop manual) removed air intake filter from frame,cleaned and replaced hose. Still awaiting new boot and adjustment tool in mail and will reinstall unit. So far seems to push and pull good air after the clean / lube of the cannister. Thank you all for your input. Sincerely, John
Any update on how this went for you? I'm about to try the same service to my vacuum shift system. I also need to adjust the shift control rod. I'd love to hear more about your experience with all this.
Even though Mike is correct in that there is a lot of info in previous posts, you need to be a VCCA member to use the Search Function of these forums.
Using that function is one of the many benefits of joining the club. Others are getting an award-winning monthly magazine, being able to search the membership database to find other folks that have similar vehicles or live near you, access to Technical Advisors, and much more.
Being a member is a great value for a very little amount of money.
