Hi there,
I have a 1972 Legrand MK. 15 air cooled super vee project that might fit your search. Probably the only MK 15 built according to the records we have from the Legrand registry. It's a complete rolling chassis, but I don't have the engine. I do have the original Hewland MK 8 transaxle that was in the car. The original spun aluminum Legrand wheels and some suspension spares. No bodywork, short of the nose. I have all the original factory drawings, SCCA log book, set up sheets, many handwritten notes and templates from Red LeGrand. The car was professional raced in the SCCA Super Vee Gold Cup series and national SCCA races in '72 through '74 and then the car was converted many years ago to race as a Formula Ford (by the gentlemen I purchased it from), and he raced it as a Formula Ford for lots of years in the SCCA SF Region.
I am aware of a number of people who have converted similar chassis using motorcycle engines.
There is a similar car in the Lane Motor Museum in Nashville, TN - a 1971 Legrand
MK-12 Super Vee - and I'll bet they might let us use their body for body molds (although that car is different, the body is similar). That car is not period correct as they show it with a wing (that it did not have) but you can get an idea of how the car would look. Here's the link :

This is a great project for someone who has the time. I have another 1978 Wheeler Super Vee and just don't have the time nor the garage space to finish this one as I had hoped. Not looking to get much for it, as I do need the garage space. PM me if you're interested and I can send some pictures.
Thanks
