The clutch in my '87 GMC R1500 is shot and I'm getting ready to pull the trans to replace it. The trans was already leaking, so I figured I would tackle resealing that as well and change the gear lube. Only thing, I wanted to get a seal kit for it but don't know what kind of trans this is. I would imagine it's a Saginaw or a Muncie? Thanks in advance! -Marc.
