Also, if you have an OEM tilt column repro lenses are available with an added "O" for overdrive that fit nicely into the original housing and look otherwise more-or-less original. Haven't really been able to dial in the neutral safety switch from the OEM column though - the truck will start in neutral but not in park.

I seem to recall grinding something on my original column and that's how I got the trans to go into 1st gear. The neutral switch never got adjusted and worked as it did before. The gear indicator just goes off the map a bit. I don't have a tilt though.
