Thanks guys. That's an old build, so maybe I'll get around to posting some more recent stuff.
Michael, you've almost got it. In 1982, both Kyle and Richard drove STP sponsored cars with the identical paint scheme, just with the colors reversed. Every now and again, they would swap numbers to do the point thing, but Kyle got 7-11 sponsorship in 1983 and changed from #42 to #7 while Richard used the same paint sheme he had in '82 just with reversed colors. I hope that wasn't too confusing. :|
