Re: bad brake booster
That is tough, I just changed out my brake booster, but I went to NAPA and they gave me the different sizes that they match up to. I then went to another company (TUFF STUFF) and after talking to them, I ordered a chrome unit for my truck and it works fine.

Re: bad brake booster
well i went to autozone and ordered the jb3 and it was the same one that i had the master cylinder bolted right up no problem but when i disconnected the master cylinder i noticed a little brake fluid on the back of the piston and inside the booster all around the plunger so i had to order one of them too that's tomorrow's project. lots of fun working on these old trucks.
