I'd venture to say that the bone yard people are right, but that doesn't mean that parts from practically any Ford column from that year and maybe others won't fit.
I had a '72 F100 that someone had hacked up the shift collar (Automatic) and moved the shifter to the floor. I took the collar from a '66 Mustang and adapted it to the '72 and it looked factory. I think you could do the same with a tilt column.
