I'm just going off of pictures and memory because all I have with me now is the frame and axles, everything else is 200 miles away.
There was no sign of any column mounted shifter or any shifter linkage in the engine bay. However there could be mounting holes that I don't remember.
Does this
cross-member situation point to it being hydramatic? The cross-member under the U-joint bolts in but no drivetrain touches it. I do remember the one forward of it does have the riveted on ears with the center section bolted in.
Transmission cover hole looks to be "custom"
