I wonder if there's any interest in shoehorning an IMSA GTO event in somewhere.

Youtube has been putting IMSA GTO races from the 80's in  front of me and those cars were awesome.
...and I have an SCX Audi 90 GTO waiting in a box for a call-up to be built with an Amato chassis

There is a IMSA provision for the GTO and GTU cars in the 70’s decade proxy, for the early Gr4 & Gr5 cars
