I just got my MCG yesterday and was surprised to see your car in there...it is also rustier than what was mentioned in the for sale ads for the car but it sure looks like you are doing the car the right way.
Good luck with the 1971 Sport Fury GT.

Trev gave the car a thorough inspection and we knew that there was more rust. Thankfully the doors, fenders and stub frame are all in good shape.
