74 & 75 Dodge Dart "Hang Ten" Special Edition Cars

Hello All.
Question,
In looking at the pictures of the "Hang 10" I noticed the AC compressor is not the standard Chrysler RV 2 type.
The high and low pressure hoses, receiver dryer, and under dash unit all look aftermarket.
Was this a dealer install option ?
Was this installed aftermarket (local AC garage?)
Does anyone think this affected the hammer price of the car ether up or down?
Happy Mopar :)
