Hope this helps...scroll down to race fiberglass stuff, they have different height AAR hoods for E-body. I'm sure they would graft one onto an A-cuda or a Duster if asked.
I'm seriously looking into the '70 Cuda glass body that they make for my next street/strip car, instead of restoring an old rusty pos. Just need a '70-'74 donor car for the vin and title lol...
