Factory vs Van tilt for a 67-72 chevy truck

[70Chevy4x4Nut]

Can anyone shed some light on how to tell the difference between a converted van tilt and a factory truck tilt for the 67-72 trucks. I am looking at two tilts on ebay. One has a curved electrical plug the other has a straight plug, and the guy says he has the adapter for it. I saw an adapter that was flat to curved and was advertised as a must for a van tilt conversion. How would someone know what he is getting? Both tilts on ebay advertise as true truck tilts. I have two columns in my garage, both non-tilt. The manual shift has a curved plug right out of the column. The automatic one I took off of a 72 blazer has a flat blade coming out with the adapter that converts it over to a curved. I am corn-fused.

Thanks

The flat one on your column is becouse the turn signal switch was replaced.
Some early van tilts had the 1/2 moon plug, while the later ones were flat.
The best way to tell is where the shaft comes out the column at the bottom. A van unit sticks out 2 or 3 inches, while a real truck one is more like one inch.
The Neutral safety switch on a truck column is mounted very low, while a van unit has it up pretty high.

Don't let the seller BS you, they truck unit is worth well over twice what a van one.

Thanks longhorn. It makes sense what you say. The one with a flat plug has an old grant steering wheel, so it is very well possible the turn signal was replaced. Seems like 8 wires is alot for those old columns.
