Scratch my last. I can use the 8000TLX on the Corvette. I can just slide them in side ways. I just checked, bunch of C6 folks use them that way because the rest of the their cars are longer. So even better as I have the longs ones for the trucks and Caprice. QuickJack (Bendpak) says it is ok too.
Found a bunch like this on the web. Found this one on the Corvette Forum. I am good with it.

I am starting to think it was blessing as the I don't think the other ones would have worked well for the Caprice. It is a big car.
