I tried one from hughs , wouldnt fit w/ my mainstuds that I had already cut down , they took it back (good guys), i REINSTALLED THE STOCK ONE , WENT THRU THAT CRAP ABOUT 4-5 TIMES , YES LAYING ON MY BACK . Finally bought one on ebay that claimed to clear the back studs , after finding the stock one wasnt made/machined/cast centered on the crank, bolts would pull it off center when tightened .< repeating myself !
