Pat Back in 65 made a dragster nose by cutting some profile ribs, hardware cloth(like chicken wire) over that and then wall plaster, shaped/sanded , waxed ( mold release) to make a plug/form to then make the body part from

lots of work but did turn out nice--won many ISCA shows--

Best part of that was that show cars are supposed to be runners and I think we had to fire it up at Cobalt hall in Detroit to break a tie with another car--when the fuel hemi lit off the other guys concided the show as they didn't have any internals in there driveline---memories
