That car was in MCG in the mid 90s in the for sale ads. A friend inquired about it and the guy sent pics of it but it was too rough for him. I think it was in Colorado or Wyoming at the time. I threw out all my issues of MCG from that time. If you find any issues of MCG from the mid 90s check...
71 GT should be orange. 71 had the HP motor. The 70 was the standard 350 horse engine with non HP exhaust manifolds with a dual snorkel with a Super Commando pie tin. The 70 6bbl was orange.
I bought a ECU from them years ago that was advertised as NOS Standard brand from the 80s, the old chrome looking ECU. What showed up was older blue colored ECU of unknown origin. Did not reply to my messages, so I kept it and left bad feedback.
