You've got to build it to suit yourself,I don't see a lot of sense in putting money into a car to have the correct Gasser look and then not be able to drive it. On my little project I'm modifying coupe doors to gain 5 inches of room,compare your car to a ford coupe and you'll see where they took the difference in wheelbase from. You guessed it,the passenger compartment. The gasser class rules allowed a 10% setback,not required. Hank
