I am pretty sure the front part of the intermediate shaft bore is smaller the rear part....or the OEM shafts are tapered ever so slightly. My OEM 1.25" shaft was REALLY tight the last 1/2" or so.....like deadblow hammer and swearing tight.

Anyways, might measure the AA parts to see if they CAN go in backwards?
