Just put jimmy/ blazer mirrors from 92 + on them .
Mine ran a 13.3 with a KB ram air kit other than that 100% stock even the original 80k exhaust, and crapping out stock plugs/ wires. I'm sure it would have gone 13.1 -13.0 after new ing parts where installed it felt alot better. But never made it back and its sold now.:frown:
