will these work on 67-72 models? came off a 75 gmc 3/4t 4x4 disc/drum and I have the valve.
thanks

Yes, but you will have to cut part of the bracket that mounts to the firewall. Very easy to do and you'll see what I mean when you go to mount it. Also the rod will need to be adjusted for the pedal. Other than that, it's pretty simple.

i just put a booster from a '92 burb on my '72 & all i needed to do was mod the bracket on the driver's side, like mentioned above you will see what needs to be done. it is simple & i also had to mod the pedel rod as well like mentioned above. it basically needs to be longer. i haven't tested the working of the booster yet, but overall it appears to be in working order. good luck!!

When I tried to mount one on my 70 the auto trans shifter on the steering column hit the booster when I tried to put it in park.
