I bought both of these from RMR when I was in Toledo. Together, they were $75.
So,,,,,the '41 coupe is either $35, or $40 LOL.
The donor kit, oddly enough, is the Revell '41 Willys street rod kit. The body, hood, grille,frame and full interior floor pan is included. You add the Willys kit suspension, interior parts (seats, etc.) and whatever engine you want.
