Chip,
You need a copy of the Elfin bible: Australias ELFIN Sports and Racing Cars (Blanden & Catford 1997)
The car was delivered to Vern Schuppan as a MR8-C (for Chevrolet) & raced as a F5000 in Australia early 1977 (6 outings in Feb/Mar).
Shipped to US in F5000 guise while Elfin built the required Can Am shape based on its MS7 sports car.
Schuppan subsequently commissioned an ex Elfin employee to fabricate lightweight bodywork.
US debut Oct 77 at Riverside.
Returned to Aus late 80s.
You may be able to get photos through
www.autopics.com.au for both the
MR8 & the MS7 (
