XXX-NT clutch on Revo?

[olds97_lss]

And to make it short you will need to dremel away part of the chassis in front of the trans, the rear of the front shock mount, flip the wire holder around, cut the front driveshaft, and redrill new holes.

Do you really need to grind the driveshaft down? Do you need to do anything to the rear drive shaft?

I just had a stock clutch spring break and I have a 3-shoe savage clutch/flywheel laying around. I just made a spacer for half of the outer cb bearing since the shaft was too short, but I'm not sure how much or how far forward I need to move the trans. From what I can tell, I need to move it 1/8"-3/16" (3-4mm) forward to get the spur to stop rubbing on the bell... well, and to line up the spur/cb teeth.

What do you think?
