Just curious, what are the differences in the steering wheels in the pinto's?  I was under the impression the early ones had the fatter mid section piece, but today I saw a 78 that had that same wheel on it.  Was that maybe replaced? 

Actually, I don't think there was ever a plastic three-spoke.  The standard steering wheel was a plastic two-spoke with a center hub horn button.  The deluxe interior upgraded that to a padded two spoke, of which there were two designs.  One went straight across, and was a bit concave, used from 1971-74.  In 1975 the outer ends of the padded spokes turned downwards a bit rather than going straight across, and it was less concave than the earlier version.  It's hard to describe without a picture.  Anyway, that remained essentially the same from 1975-80.  The three-spoke metal sport steering wheels came on certain models and were available as an option on other models some years (not sure which).  Sorry I can't be more specific, but this is more or less correct.

I know on my 77 I have a steering wheel from a mid 80s Ford F150 & it works fine. The only major difference is the center logo

Cool, no that helps, the one I was thinking of was the 2 spoke horn bar one with the deluxe interior.  Mine has the 2 spoke with "button", so thank you!
