Will they interchange? Found a really nice green steering wheel off a van to match my green interior. If it will fit I'll pull the trigger on it.

The only problem might to the diameter of the wheel. Too big and it takes up leg room.

The 70s had Big Wheels to start. I would almost think it would fit. Daytona wheels fit the trucks. If its cheap enough its worth the gamble. Or if you gotta pull it at the Jy count your splines and take pics before going. Maybe look into Adapters and see what else the adapter fits? Let us know

The van wont have the lock in the column but the truck will.

That won't make any difference on the steering wheel.

if the van is at a jy, see if they have a truck, and try the van wheel right there.

In some years the steering wheel is different between a tilt and non-tilt steering column. (This may not be of concern. I can't recall if the tilt column was available in 1976 trucks.)

The wheel was on ebay. I went ahead and bought it. It looks real nice. If it doesn't fit I'll have a really nice green van steering wheel for sale for all the van guys here. I like the looks of the metal horn button on it better than the truck wheel. Thanks to all who posted.
