Does anyone know if the interior door
paint matched the interior or exterior
color for 67 Camaros?

How about the door jams?

It's impossible for me to tell considering
the car has been painted a few times already.

I'm going with a black interior, though it
was originally gold - blasphemy!

Door jambs and inside of doors was painted body color. Note that the screws that hold the door latch are not body color in 67. They are silver cad plated. In 69, they are body color....not sure about 68.

But all of the inside, door and quarter tops I’ve seen on 67’s were painted interior color.
