I realize things have gone up, but...My Hurst Competition Plus shifter on my M-21 has been jamming from 2nd to 3rd. Since no one seems to designate a shifter for a 73 Camaro with an M-21 and a console, I called Summit. For the shifter and the adapter kit they quoted me $610.90 with no guarantee that it will fit. They said the shifting rod length may have to be altered, or the mounting plate could need re-drilled. That's probably just as bad as the situation I'm in right now, having to start from scratch. I was looking into rebuilding it. Steel bushings have been installed, neutral gates are in alignment with rod adjustment. Seems to be excessive side to side play when in gear, or is this normal?
