Full manual Valve Body, and Diff. Questions

Yeah, tell me about it. I feel like a real retard for not checking this sooner. I guess that's what happens when you take the buyers word on everything lol!

So would it even help, if I installed the kickdown linkage, and new shifter, or should I just pull the tranny and have it rebuilt?

we all learn things the hard way sometimes. Most likely it's toast since your description in the other thread sounds like a burned clutch pack but you will have to install the linkage sometime so you might as well hook it up and see what it does. Can't hurt anything.
