I thought it would be really nice to put a brake booster on my '53 3600 as I saw them all the time when just browsing through catalogs. What I guess I didn't see, was that they were for the 3100 and only an automatic? I've got the 3/4 ton with a manual transmission. Of course, the transmission isn't in it yet, and the engine is a 235 out of a '55 car that had a hydro-glide - but all I have is the manual. Am I out of luck for a brake booster? I've looked at every site I can but I would love to be wrong if someone can point me in the right direction.
