I don't know that it's a shorter version. The steering column does not include the shaft (the lower steering shaft) that goes down to the steering gearbox. The column just goes through the dash and the firewall, and them stops several inches forward of the firewall.

So the same steering column could be used in a regular car or truck. I don't know if it is, but it could be. If you've got several columns lying around from Chevy trucks, measure them and see if they'll fit. You also will need to see if the female upper splines on your lower steering shaft will fit the male splines on the end of the steering column.

Like I said before, I don't know if the lower steering shaft will be the correct length. The OEM steering shafts did not have an adjustable length. You can get a new shaft that has adjustable length amd needle bearings in the u-joints from Borgeson, but they may cost more than you're willing to spend.
