This post will show the original firewall modifications, mainly by lowering the distributor depression, and then filling in the void above with an aluminum close out panel, that will be bonded to the original firewall.
The close out panel fabrication involves using the Baileigh bead roller to create raised areas to give a factory Chevrolet look.
The final set of photos show the cowl bead build process, to correct poor metal structure from the original one, to round out the metal work on the front of the Chevrolet cab.
