Probably not your issue; but make sure the TOB is seated properly in the fork.

A good litmus test is with the car AT REST, try to get the trans into - and out of - reverse nice and clean. If you can, the clutch is adj properly. This doesn't necessarily rule out the clutch but its a good indicator that the adjustment is proper. Do you have a Centerforce clutch with those little weights wired on? Sometimes those little wires can cause problems.

If none of the previously mentioned things in this thread solve your issue; check that pilot bushing and the pilot on the input gear (the smooth tip on the input shaft rides in that bushing or bearing that's in the back of your crank). If you have a needle bearing in there; get it out. If you have a bronze bushing in the crank, check it with a magnet. if the magnet sticks; get it out. Replace with a premium bronze bushing that DOES NOT stick to a magnet. We make them; but if you're not in the northeast, its more cost effective to drive to Napa and rummage through their box, checking the inside dia AND the outside dia with your favorite magnet.

Needle bearings are great if you want to futz around with a dial indicator, trying to dial the bellhousing register within .002. The bushing can take a small amount of misalignment and still work properly. Do NOT use grease on the pilot or the ID of the bushing.
If the tip of your input is discolored, scratched or pitted...it should probably be replaced, although in reality, a bushing shouldn't be bothered by this if the damaged area is very small and localized.

Since you'll be under the car anyway, drain the lube from the gearbox and inspect it. Refill with GL4 multi viscosity 90wt NON Synthetic. We like Sta-Lube's SL24229 (1qt bottle) from Napa
Sorry for the lengthy post
