Late model power brake booster upgrade

[Myself]

I just finished this up and thought I'd share what I've learned. The brakes were not working on this truck and the owner said "Do whatever you want, just make them work." I was heading to the junkyard anyway to get some other parts, so I was on the lookout for a brake setup. This particular unit is a dual diaphram booster from an '89 Chevy 3/4 ton van. The whole thing was $35. It bolts straight to the firewall, instead of a bracket like the original. This truck had already been changed to a ''75 ish setup at some point in time. Here are both of them.


I decided the first step would be to remove the bracket from the old booster. I just had to grind through the rivets,


and pop the brackets loose.


The '75ish brackets were a little bulky for my tastes, so some trimming was in order.


The long studs on the newer booster also need trimmed. About 1/2 way will do.
