They ran a '65 Coronet AWB, IIRC. I also think they briefly had a Challenger (but it may have never been raced, only tested).
Edit: I have been looking on the internet to check my facts, but can't find anything. I really do seem to remember them having a Coronet. Maybe they rebadged it as a Belvedere for a single race or something. I seem to also remember them disguising a '70 Cuda as a '71 for a race or two.
