Steve, I have several pictures of my bosses original unrestored Hemi Dart on my computer at work if you send me a e-mail I will send you pictures of the areas in question. I can tell you that the underside of the super stock cars were painted black just like the trunks and engine compartments. I took several pictures last year and posted them here on Moparts. Sounds like a nice project let me know if I can help. Here is a picture of the car that I have on my home pc.
