70's truck column vs van column

[mygirlz55]

I'm in a bit of a pinch with our Camaro clipped 55 TF build. I've came to the point where I need to purchase a steering column and get the truck closer to being road ready.
I'm unable to find a van column to use and want to know if a 70's truck column will work for the time being. We don't have enough in the budget to afford a flaming river or ididit column right now, so I need to find an alternative.
I believe the only differences are the key switch and tilt but not 100% sure.
Has anyone installed a 70'S truck column in a Camaro clipped TF? if so, any help/pics would be appreciated.
Thanks
