Thanks for the pointer! I'll check around my LHS's to see if they have said parts.

Did you not run into chassis-flex problems running a mount like the TC4's? I heard gear-mesh horror stories if you didn't have a good mount that either a) reinforced the chassis well or b) was mounted directly to the transmission

I was thinking with the TC4 mount of drilling a nipple hole in the top of the mount to connect a turnbuckle to the tranny from the mount to help keep it lined up under high chassis flex situations (bashing)
