I use the stock steel ones in my vintage racer and have never had any trouble...I have an extra set NOS in the GM box if anyone is interested. e-mail DIRECT redvetracr@msn.com

Solid steels, tune with polished case for the best results.
Fiber......junk, look at the pictures of the fiber clutches in my diff post. They broke down before they were even in the car.

Use the Tom's Differential solid steel plates NOT the "daisy cut" GM service replacements. I usually find several broken pieces in any "daisy" type clutch pack. The reliefs were done to aid lube circulation but make the plates fragile. I also alway install the pre-load springs now for long term service life instead of tightly packing the clutch pack, I do set pinion gear clearances properly and let the springs do the rest of the work.
