'69 Barracuda T56 swap, floor, cross member
Done got sick lost a couple weeks but fully recovered now feeling great and back on the project again.
Formed up patch for front half of tunnel. It has around 1/8 - 1/4 inch overlap with floor in its current state. Could just overlap weld in seal it and be done with it. Gonna sleep on it and probably go butt weld though.
Note no more bent over pinch weld between floor and firewall. Floor is butt welded to firewall where bent over pinch weld used to be.
