833 Transmission won't disengage at stop after 100 miles.

for adjusting the Hurst shifter on an a-body, use a 1/4"(IIRC) twist drill shank inserted into the holes in the shifter's fwd gear levers to position the 1-2, 3-4 shift levers properly. However, I've always found that the reverse lever never seemed to line up and shift properly, so I adjusted it totally separately from the fwd levers.

Yep, I found the same with my alignment pin. Reverse needs to be eyeballed.

I did the pin set up after rebuilding the transmission a couple thousand miles ago. I ended up chasing my tail - turning out the 1-2 linkage maybe 4+ turns and the 3-4 out at least 2 turns before it started shifting 'kinda' smooth. I just replaced the new clutch, and old pilot bushing, disassembled, cleaned and lubed the shift gates, and finished reassembling it all again, and it looks like I need to start turning out the 1-2 linkage a turn at a time again.
