A833 In Truck

Your '83, does it have the "humped" up floor in the middle? Picture of the middle of the floor would be good. Do you have the bracket for the "truck" application to mount the shifter to the tail housing? Was this truck originally a 4 on the floor OD? FYI, I'm doing the same thing.
Fiberglass floor hump. 2wd truck. I have that bracket and linkage
