My friend has a 65 conv. - I coded the car and it was originally gold with a standard interior package. A previous owner had painted the car red and put in a red interior. The dash and interior doors were painted a brighter red; however, the seat covers (Pony style) are a deeper red. Is that a proper color scheme, or should all of the red color be similar. Also, what were the changes in the interior that made it a Pony vs. a standard.
