I was in the bone yard last week lookin for a T-5 trany for my 3sp swap. I found a 67 chevy that had the compleat booster MC and all the brackets the old man sold it to me for 25 bucks I just wanted the brackets but I had a vac day today and got board so I cleand up the booster and threw it on not expecting it to work but wanted to do a mock up to see if I needed anything else. So I got it all hooked it all up used my MC and started it up and to my amazement it worked great. So I left it on. I was gona order a new one on tuesday. so I think ill see how long this one last. The old guy has about 15 trucks I'm gona go back over to check them out some time soon.
