The AMC15 will take more abuse then most give it credit for. I'm still abusing mine. It's 3:31 twingrip with 255/60/15's and if it was weak it would be broke. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrc II " Chronic Pain Hurts" -------------- Original message ---------------------- From: Frank Swygert <farna@xxxxxxx> > Don't sell the 15 short!
