[PONTIAC DUDE]

Use the steel bushing washer kit. Make sure you have the good spring loaded clips, not cotter pins.
Back in the day I use to lead the 2-3 shift in the adjustment. Hurst to get certain shifter and linkages to fit had rather wild curving linkage which promoted flex. Also the thin rods are the major contributing factor. I used to weld inforcement straps to the Hurst rods for more support. Mig has less heat displacement
Also engine/frame motor mount flex will lock up the shifter even thou both are connected to the same unit.


Best shifter I had back then when I raced MP with a 68 Camaro was the Verti gate, but required cutting the tunnel hole larger.

You can go inside your tranny and shim up all the gear sets to .010. Big, big difference. I use to use the BW 4 spd dogs as the 3 keyways were wider and shifted better. Plus they were harder. Make sure you have the proper clearance on the slider and brass syncro. Most after time ride right up against the steel teeth which will cause issues. The input shaft always needed a lot of shims to get rid of the endplay.
