I researched this question a few years ago. On the J, the only steering wheel available was the rectangular one. On the K, the rectangular wheel was standard, the GM sourced tilt wheel was optional. The tilt wheel assembly included the steering column which cannot be used with the rectangular wheel and the round wheel on the GM tilt unit cannot be interchanged with the Chrysler non-tilt column.

Thanks to all. I believe that they all had the "square" wheel, EXCEPT for the tilt wheels which were round in every instance. I do not believe that any tilt wheels were square. I THINK I can answer your first question. The standard wheel for both '63 and '64 was the rectangular wheel. However, in '64 there was the optional (I THINK) for the first time a tilt steering wheel. It was larger and is round. The column at that time was made for Chrysler by GM. I have been told that GM still has (or had) the turn signal switch as it was also used in Buick and Cadillac. I do know the number of splines on the shaft is different at that time, so when I want to have the round wheel reworked on my 300-K, I can not substitute a rectangular wheel! I have also seen a trashed, '64 Imperial with the same column and wheel.
