A body Mopar cars made?

Yes, Revell also has (had?) a '69 Dart GTS. They both have big blocks, but the '68 has a vinyl top and the '69 doesn't. Different grilles and stuff too. Revell also did a '68 Hemi Dart superstock car. I think that one is actually still in production.

Don't forget about all the Volare/Road Runners that MPC did several variations of. There were MPC '69 Barracudas too, still easy to find.

How about the currently available AMT '71 Duster 340?

And... Revell 1962 Dodge Dart 4 Door Hardtop. Hard to find and very expensive.
