Not sure about 58's, but red wheels were an option with full wheelcovers, and body color wheels were the option for small "dog dish" hubcaps. Black wheels would have been standard. Again, not sure that is true on a 58. Whitewall width is one of those things that people worry too much about, in my opinion. If it is 3" vs 2 1/2", who really cares? (Concours and other very high level judging aside) Now if they were like a four inch whitewall, they would just look too big. Can't help ya on the possibly extraneous bombsight.
