I need help figuring out what I need to convert my 1970 Buick Skylark Custom 5.7/350, 350 THM to a manual 4 speed Muncie Transmission. I'm not too sure on what I need to mount the clutch or where to get the parts. Also need a little advice on how to correctly mount shifter. If anybody knows anything else about what i might have to convert to make the switch work would be greatly appreciated.
