difficulty adjusting clutch sweet spot

I have this posted at Moparts.org also, so pardon the double post.

My car is a '65 Barracuda with a 360 and an A833OD gearbox. Both have recently been rebuilt. When I installed them I also put in a new Centerforce clutch, pivot and adapter plate, and throwout bearing - all new from Brewer's. Lately I've been reading about proper clutch adjustment and I just can't seem to get mine correct. I always seem to have noise down there and so I'm finally investigating.

With the inspection cover removed, I can measure out 0.060" clearance between the clutch disc and the flywheel. But when this is so, the throwout bearing rides on the clutch fingers. If I adjust it the other direction to just have the smallest gap between the throwout bearing and the clutch fingers, the gears grind.

In other words, I can't seem to split the difference between throwout bearing clearance and disc-to-flywheel clearance.

Any ideas what's happening here?

Thanks,
Marcus
