Wow, indeed! Tom Null in Los Angeles also has a 2-door, making 3 in existence. I also know of one more that was scrapped in the 1970's, but details survive in the registry, as well as pics.
The trunnions were the larger trunnions for the 226-engined cars. Check the bolts over carefully, they have a tendency to gully and give way, possibly losing a wheel. Happened to me a few years ago with Old Toby. The trunnions are somewhat easy to find but the bolts are nearly unobtainium. Duane Hayes may have them both, also try Bruce Wadlin at Obsolete & 4 Wheel Drive in Bradenton, FL.
Nice car. Interesting that it is not two-toned. Could you send me the paint codes and all the other codes? Click on the link in my "signature" for other interesting info about Aeros as well as registration.
