And then then getting the drive line rebuilt and balanced up at sixstates here in Portland.

Exactly I think your right on the money. Is sixstates any good? I was thinking that or go grab a junkyard ds and try that. I kind of like the drums, they r heavy and a pain but they stop a freight train. The disc option looks cool too.
