We are set up with dynacorn and have sold the Front rail assemblies and other pieces,
To clarify the inner structure between a cuda and a challenger are interchangable Except, the rear foor well ( challenger are 3 inches longer) , and trunk floor ( only because the fuel filler location ), speaker shelf rear roof bow, inner quarter peices.
frame rails are the same 70-72 E, Front floor and a pillars and firewall forward they are the same.
Dynacorn Shares stamping (triplus) with Goodmark And sherman and possibly some of AMD, So the Quality from what i have seen is pretty good,
for the rear assembly to work for you on a cuda you will have to change the trunk flooring OR cut the fuel filler hole for the cuda out and use that to patch the challenger location. dimensionally the under seat pan, rear rails and trunk floor are the same,
Just an Fyi there is 7 of these in stock, Shipping will mostlikely be upwards 2-300 range bcause of the size. Let me know If we can Help.
