Finally finishing up my 70 DY3 440-6 R/T SE Challenger. My original headliner backing board (perf. particle board) is warped in a few areas, and I am leary of trying to straighten it and use it, for fear of it rewarping down the road.

Does anyone know a source for a new/repro. board? I think finding a good original would be tough (and expensive).

Thanks for any tips!
