Hello, <<<Too early for Arvinode exhaust, should have been a transverse system.>>> I have been in contact with the original owner and he states that nothing was done to the exhaust on the car from the time he picked up the car, until we purchased a few years later. Also, he did not drive the car enough to replace tires, brakes, shocks or any other consumables.
I can say that the original exhaust on my car did NOT have the rectangle supports on top of the 'mufflers', the exhaust system was one pc. from H pipe back to the turn downs at the rear valance.
The car does have the 64 1/2 hood & headlight buckets, heater switch, spare tire bolt. The car is Rangoon Red with red interior.
