The following pics probably won't clarify much, but I really believe that the dash pad should be dark green. Darker than the lower dash.

H6F8 Cuda with a restored interior. Note that the dash pad and lower dash are almost the same color. I don't think this is correct.




Here's a T/A. Probably restored interior based on how nice the carpet color looks. Note the dash pad is darker than the lower dash.




Challenger with green cloth interior. Dash pad looks dark. Note carpet fade so it might not be a restored interior.




This Cuda has the green bench seat. Here it looks like the dash pad is lighter. The carpet is also faded, so maybe the dash pad is too?




One final picture of a T/A interior. Dash pad is darker. Probably restored.
