I run Scat Rally seats and matching brackets on a '70E (Summit). Good side bolsters and comfortable (for me) on long trips. 2,100 miles in 3 days no problem. As far as steering wheel, I run the original (big) rim blow. The one I like is the Flaming River re-pop rally wheel... but have not been willing to shell out $300+. The Grant re-pop is nice but larger diameter vs original and Flaming River re-pop.
