Bandit II's are exactly were made from the same company that made my Pro/Am. They only made 500 in 1991 and 500 in 1992. They only converted "Formulas", so some of them I believe can have a 350 (not too sure tho). Choo Choo Customs aka Chattenooga Customs were bought out by "LA West" which does Convervion Vans.
Redraif made a cardomain site dedicated to rare F-bodies, with alot of pics of the Bandit II's in there.

AFAIK, they had nameplate + production # badges on the dash, shaker scoop (functional or not, dunno), Razzi Body Kit, and some other minor things
