I have both headliners,and backing boards, I thought I could do the same thing seeing the challenger board was busted up,.....the cuda board is much smaller, the front section is the same, however the rear is about 4- 6 inches too short and contoured differently, there was some guy over at DC.com making fiberglass repros, think he had plans of selling them thru Dante's?......for about $500?.....never followed up on it though, figured I find a board at a swap meet?
