Looking for Vinyl top replacement

I'd certainly try Legendary. I think Classic Industries may resell a lot of Legendary's products, whereas Legendary is a manufacturer.
Legendary lists Pearl White Boar Grain for C-Bodies. Maybe they can get a piece large enough for your 'Cuda.

Bingo!! Legendary said they can just sell me whatever length of material I need, which comes in 54" width. So for just $64 I can replace my original top with a piece of material in the correct color and pattern. Thanks for the help!!
