From what I was told it was when the marauder was in pre-release, so all the parts were made, and in existance, but the cars were either not built/not delivered....
I figured I can modify the LX sport piece to hold the gauges easy enough, just need to get it..
Thanks for clearing up the gauge thing you had me confused, yeah the autometer OP looks just about identical, I stock them all the time, they are nice piece I used to have one in my lincoln....
