Joe this is a great project. Great start, I would suggest coming up with an inner structure to reinforce the body. This would be needed in real life and also to keep the resin body from snapping at the doorsills.Jim Lytles big al 34 had a lift off fiberglass body with opening doors. You might also consider onky opening just the drivers door for added strength . Also full size the body would be lift off so access wouldnt be an issue,
