[s-cars] Steering wheel options for '92-94 S4

[RJA]

I'd like to replace the steering wheel in my '93 S4 with one of the newer
style or aftermarket, but I still would like to keep the airbag.  Do the
steering wheels from the new S4's fit the UrS4's?  I like the 3-spoke wheels
with Audi sport logo, what cars were they used on and would the fit the '93?
Are the airbags compatible or do they need to be swapped?  What kind of work
is involved?
