Hey, thanks so much for your response and details.

The manual shift levers occasionally don't realign on the 1-2 shift and hangs up. We are attempting to install new "shift levers" (R-1/2-3) and the "selector" in hopes of rectifying the hang up issue. It appears that the column shift shaft/rod that runs down beside the steering shaft is threaded into a u-bolted bracket at the bottom of the shaft adjacent to the steering box. Does anyone have any detailed information on how to go about removing the shaft/rod and old shift levers and installing the new ones? Steering wheel is off and we thought there may be some way of turning the shaft/rod to remove it from the u-bolted bracket at the base by the steering box but we haven't discovered anything. Also, someone has installed a radiator clamp around the shift shaft/rod to keep the levers in position. Evidently, there was some type of factory item there that was lost at some point and we need to obtain that item also. It should have a locator hole to slide the alignment pin into the shift levers to calibrate the shift rod arms. Can anyone help? Thanks!
