From what I noticed in earlier times, all of the C-body steering wheels should all interchange, except possibly for the Tilt-A-Scope wheels, in the 1970 era vehicles and probably up to 1978 also (just my suspicion). In other words, a non-rim blow steering wheel should bolt on. I suspect that if there's anything different in the way the horn contact wire plugs in, if you get all of the related parts, they should swap out. Again, that should work for the non T-A-S columns. On the new steering wheel I bought from Chrysler in the late '70s (with the rim blow installed), there's a recess on the bottom of the wheel that would coincide with where the tilt/telescope "lock lever" is. It might be possible to grind that deal out too and then put the longer brushed stainless sleeve on the back of the non-telescope wheel (maybe). But I'll bet that if you find a middle '70s or so steering wheel for a tilt/telescope column, it'll probably be an easy swap in
place of the rim blow wheel.
With the correct paint, the steering wheel can be recolored too, plus the center pad redyed to match.
These are the basic things I recall when I was researching getting something else on my '70 Monaco with the factory rim blow.
