Nice progress!
If I recall correctly, all the white, 1973 automatic SD Formulas are on the registry! Eight, if I remember right. One shows as being scrapped in England.
Bob Ashton who runs MCACN would be the guy to talk to about a display.

I am bringing the 73 Formula SD for the vintage certification which has its own display area. And as an added bonus, the original owners, Enrico and Lenora Stein are coming up from Scottsdale to be reunited with their car. They postponed their 50th wedding anniversary and are using this trip as their anniversary celebration.
