Hi guys,
I'm looking for a used TH 350 for a '79 Firebird project. I have a fresh 350 cu. engine for it, but I have been out of the scene for about 8 years, so things are a little foggy right now.

What should I look for when buying a used trans? How long can they sit before clutches go bad, etc? What is a good price for a used tranny in decent-good shape? Any other tips/info much appreciated.
