A lot of the OEM Hurst A-Body shifters do not have the Reverse lever drilled, up to 1971. There is a metal rectangle sticking down on the housing, front and rear that will also "index" the neutral position for the shifter. It will usually be within one turn of the neutral position in either case. In other words, check neutral position and be prepared to add or subtract a turn on the rod adjuster to hit the sweet spot.
