I'm not sure about the truck. I know the SVT Lightning IS classed. I remember seeing something somewhere about a "Truck (all)" type catch-all classing somewhere. Of course if you're not running a SCCA event, things will be totally different.
As for the Saleen... Maybe one of the SP classes (I'd have to check the rule book, don't have it handy) or maybe SM2? I forget what the cutoff is between SM and SM2, I'm pretty sure I've seen worked over Mustangs and Vettes in SM2.
Why not just have them run Novice or maybe Time Only (if the club has such a class)? Here, the only thing that prohibits you from running is R-Compound (or obviously race) tires.
