As far as the original steering wheel:
More than a few customers spec'd out that they wanted cruise control on their Fox Body Saleens. If you wanted cruise, (prior to '89) you got the Ford factory steering wheel. I believe that Saleen would have shipped the Momo with the car, in the trunk.
Doesn't everybody take off that pesky coil cover?! lol I see more cars without it than with, these days.
