Only 1948 or earlier bodies allowed in Vintage Gas Coupe.
Not a problem.
The 47's and 48's are nearly identical to the 49's.
I suggest a Starlight Coupe - the round rear window section might cut the air better.
See post #1. A 49 or 50 with a 47/48 front end and fenders would be legal -- same tin on main body section. The Commander has a nose with wheelbase extended 4 or so inches over the Champ, so would be the best for higher speed classes. A 3 inch top chop is also allowed in VGC.
