Just installed a top loader from a 68 Mustang. It came with a hurst shifter. If I try to shift quickiy between 1st and second it's very stiff and grinds. I'm thinking maybe the syncro is bad. I havn't tried to adjust the linkage at all because it shifts just fine at a normal shifting speed. Also, downshifting to 2nd is just about impossible unless your standing still. Any help is apprieciated.
