My 86 G63B has 162,000 mi. on it and the clutch is beginning to slip under load...does anyone have a recommendation for a clutch?...I went to Exedy website and all they offer for my truck at this time is OEM....I'd prefer a performance upgrade as I sometimes carry about 500 lbs of equipment in the bed of the truck. I've been to several websites and don't really know alot about the other clutches, obviously I'd like a great price but more importantly is....reliability. Thanks in advance.
