More fabrication

The middle of the rear subrail is now tacked in place. This area is made up of a 4"x1" 12 gauge angle that is match arched to the frame rail. On top of that is a 3/4" .083 wall match arched square tube that extends forward inside the original subframe and extends to the rear of the body. With the addition of 3 tube cross members, the subframe and floor are then capped with the 16 ga. floor and all is plug and seam welded into place.

The 4x10 sheet was sheared to my drawings and came out perfect. I then found a sheet metal shop that would brake the pieces after I trimmed them and layed out the neccessary actions on the sheet.

The firewall was cut for the setback and
high enough for the distributor. I knew that the template and the new hump would only be close. Rescribe the opening and cut to fit. Hours later, it finally slid in and I was able to scribe the inner firewall face for its cut.

Back in for final trimming/filing and then this limp noodle gets tacked together. Can I get it back in the cowl?

Now that we have a partial box, things are a little different than two flexible noodles. More trimming tomorrow, the joints must be as tight as possible prior to welding.
The passenger side bottom needs to be relieved about 3/32" moving the firewall insert to the passsenger side.

After this final trim (???) the extended lip will be scribed for cutting.

I need to fit the front floor to this firewall prior to cutting and welding the firewall in place.
