what brake booster will work on my 69

[jamon8]

I need to put a brake booster on my c-10 what years will work. I tried an 89 and it will not work.

I need to know also if I need to change the brake pedal and the pin

thanks for your help

Unless you have a valve cover interference problem like on a BBC, I would use a 69 ---(67-72). You just need the fulcrum with bracket and then a 67-72 1/2 ton booster. This is the least hassle.

I got a '70 out of a Burb off Craigs List for $20. They aren't too tough to locate.

jamon8,
If you still have drum brakes front/rear you can use a 67-70 3/4 ton double-diaphram booster with the shorter brackets. Those brackets are shorter, like 3.5" while the bigger ones on the delco-morraine boosters are about 5". 71-72 3/4 boosters are different though, they have a rod with a different throw because they are coupled to a disc/drum master cylinder.
The 67-70 3/4 ton Bendix boosters are deeper but not as big around as the 71-72 ones and are easier to spot.
Just remember to get the brackets too.

I forgot to mention that I am putting disc brakes off a mid seventies truck but it was a deisel and was hyda-boost

Then you will need a disc/drum m/c on a delco-morraine booster- and some long 5" brackets.
Autozone has the Booster and M/C for the 71/72 3/4 ton for $109.00 plus a $35.00 core charge.
Board members will have the brackets if you ask.
New stuff is good. New disc brakes are good.
