I've got pics of one such car, but I can't post them here. The interior has a couple shades of green in it. Dash pads, console upper door panels are a darker green while the rest is a medium green. This is pretty much the color combo for the 69's but the medium green is somewhat brighter. Its tough to get trim pieces for green cars. Especially stereo speaker grills.
Sorry guys, but I know this now as I have the car in my driveway. (see other WIW post) I had not seen the actual car since it was hidden under a tarp but the PO told me it was green interior and I had never seen one in a Mach before so i was wondering if it was a real mach. Turns out it is of course and green did come in the car originally.
