Cool :)

I'm not sure if it's the same thing you're talking about Bonne, but some cars actually had a 'backdrive' rod. It connected to what looked like linkage for an automatic transmission, and it actually connected to the column like an automatic trans shift rod. It would move the column collar to reverse, and I'm not positive but it may have also required you to put it in neutral to lock the column & take the key out.

It's the same setup. You just need the even more rare dual bolt pattern bellhousing

My '77 Nova (X-body) was equipped with a 'backdrive' rod that would rotate the steering column collar into reverse position to activate the backup lights and release the key from the ignition switch.
However, my '79 Cutlass (A/G body) had a key release lever on the column instead. I don't recall where the backup light switch was or how it was activated. It probably wasn't on the transmission because I was breaking Saginaws left and right and don't recall any wiring during frequent replacement.
The BW/Tremec T-56 has a built-in switch. And twin overdrives. 8)

But what about the pilot bearing issue with a non manual trans sbo crank? I was under the assumption that the crank has to be swapped or drilled out for the bearing...correct?

I didn't even think about the crank

Doober I was talking about this abortion. First pic is the mount/linkage, second is the switch itself. Third pic is the Hurst switch. I believe the backdrive linkage showed up around the same time the screw-in switch did.

FWIW I have never seen a Pontiac crank that had not been drilled for a pilot bearing. Even on years that no manual trans was offered at all.
