Thanks Kip, i went to some sheet metal guys around here and nobody can bend 1/16" aluminum so I'm just gonna cut slots in one side and bend / rivet the flat side to wheel well. Then rivet aluminum to new panel in between cut slits.
It appears they used a tape with fibers running thru it back in the day. Am I correct in assuming now people use Trempro or another caulking in place of that?
