Yup, you're right! It is a dragster body. Probably one of the ones made by Lloyd Mosher back in the dark ages. I've always wanted one of those.
I'm surprised to see one that hasn't been cut up and used yet, those wheel wells are "as-delivered" and the price is absolutely terrific.
OF COURSE, if it were closer it would ALREADY be mine . . . ! ! !
Nice find.
