I put an 80's wheel on my 74 ( 2 pins ) and it works fine but I have not as of yet gotten the turn signal canceling to work. On my 66 (1 pin) I'm eventually going to do the same thing I'm solving the pin problem by swapping to the later (2 pin ) style wiring harness in the column. The two pin version uses a horn relay and the one pin version does not. It would not be a bad idea to add a relay anyway.
