Some later model mopars had tilt & Telescoping steering columns

The column was a GM design if I remember correctly. One of those columns may be modified to fit the Challenger.

As for removing the Crush Can yes it can be done. Two methods I have used.

Put a tough wheel and adapter which will cut off a few inches and you can still see the gauges fairly well.

I ended up with a Grant GT wheel and their adapter which took the whole length of the crush can out. Works great for me (over 6') but the gauges are covered by the small diameter steering wheel.

The only drawback is you loose some of the safety of the collapsible steering column.

You know my motto..

No Airbags, we die like real men.
