The 1998 race might get a little ridiculous to figure out based solely on the fact that it was an actual points race for the Winston West guys therefore they made up the majority of the field. And there seemed to be a A LOT of the West guys that came with T-Birds and ended up racing with Taurus' or had a number change before the race, or *insert other random condition here*.
I think the '96 race is definitely doable - I've already had that conversation with
@Majesticexpress - and a handful of the cars I made for the '97 are literally the same exact car the driver ran the year prior at that race just with some different contigs and what-not. So I snatched the image folder you dropped over there on his thread as well. An HUGE thank you for compiling both of these image dumps!
