Correct, Mark. I also have copies of the original blueprints of the car (engineering drawings) that have dimensions, accurate curvature, angles, etc. Before final execution of the forms and after the scanning of the model, the dimensions will be verified against the blueprints and adjusted accordingly. This should yield a perfect match.
Now, these cars were all hand built so there are variances between cars. Take the hardtops that some were equipped with. Each one was unique to that car and wouldn't fit another since there would be minor variations in body panels where the tops mount on the body.
That's another reason for the full sized mockup. I can then compare to the real thing and sign off on the final design before I move it to production. See?! Not only do I have a design team, I also have a preproduction inspector and a production staff!
Yes, Vintage Coachworks, a division of Restorations by SuperDave, a corporation of DaveCo, is in its infancy!!
