Hey my dad and I just replaced the shifter box in our 59. Shifted fine, reverse works, then it locks up. Pop the hood, fiddle with the upper reverse lever. Shifts fine again, then it locks up.

Any idea how to adjust this? We are very frustrated.

We just kinda bolted it on the column, tightened the shifter linkage, popped the 2 shifter rods back in and tried to run it. Is their a good explanation somewhere on how to set this up?? Like what position should the column shifter be in when you connect it to the box shaft?

The box shaft is splined, but the column shifter linkage does not seem to be?

THANKS
