The seats are done in vinyl (as original for that car) and the wiring was removed from the car while it was being restored , then repaired (where needed) and re-taped with original style tape (by me) . It's hard to believe that it's the same car that sat next to the shop rotting to death for many years

.
There IS a trick to the hot car situation (at least for the early cars) , I'm not 100% sure if it's still possible in the 74+ cars (you can look easy enough) . Pop the hood & look on the passenger side of the firewall , where the brake/clutch master cylinders
would be on a RIGHT hand drive car . There
should be a plate/cover there with 4 screws holding it down . Remove that cover & make another "dummy" plate out of METAL , only make the new one with a hole in it (about the size of a clothes-dryer vent hose or something similar ... getting the idea

?) . Now run the dryer hose up to the radiator shroud panel up near where your oil cooler lines pass through (you may have to "modify" the panel to allow the hose to pass through) . Fasten the hose along the fenderwell , away from the engine & you're done ... fresh air ! It's like a direct fresh air funnel into the passenger footwell , which is better than NO air into the cabin

. If you do not run the hose up behind the grille , you'll just be pushing HOT stinky engine air into your car , and that's bad news ! The LAST thing you need is MORE hot air

!!!!
Have fun !
