just bought a small block 350 bolted to a sm420 which has a late 60s vaccume t-case atached to it. planning on doing the swap soon to replace my smoking f motor. this vaccume stuff kinda scares me. i like the one i have in my stock 72. do you think i can just un bolt the older style t case from the drivetrain i just bought and simply attack the one in my truck. of course i would remove the one from my truck first..... etc thanks for any help. should i do this.....etc
