There's plenty around. Try to get 99+ as their motors were torquier and they didn't come with the awful looking chrome trim that the earlier 540's came with. I believe later 98's didn't have this trim as well. Otherwise you'll spend a few $ like I did to swap it out for the newer "shadow line trim". The best bang for the buck mod on a 6 speed would be the differential F.Y.I. Factory comes with 2.81 open, if you throw a 3.15 from a 99+ auto sport on their you'll run mid 13's in the 1/4 mile like I did..all day long. It turns it into a real beast, I suprised alot of people with that car with only a few bolt ons.
