Thanks for the replies.
Cosmo: I had the frame straightened after I had removed all the sheet metal last Janurary. The frame looks good, and any gross measurements I've taken tell me the frame is not bent.
Dave: You know, I thought about the column being bent as a possibilty, too. It LOOKS straight and when I had the steering attached for towing to the Body Shop, it steered fine.
Any other ideas or suggestions are appreciated.
Thanks, guys.
