Info Wanted: B/sports 1958 Nats Don Simmons

I got an inquiry from a guy looking for info on an Austin-Healey with a 437" Buick motor that was a class winner at the '58 Nats in Oklahoma City. The owner/driver was Don Simmons of Tuscon, AZ. I found him listed in the program here: http://www.jalopyjournal.com/forum/showthread.php?t=265313 I've seen some amazing connections of long lost cars on the H.A.M.B. Anyone who knows the car or the driver, please post up.
