2/17/24 The last piece of the puzzle (the firewall patch) finally came in. This is the last of the metal work on the cab. Yea!

I received a firewall patch from fellow ‘Bolter “KCMongo”. He is a great resource to get patch panels, cut from original trucks and shipped right to your door.

A previous owner butchered the firewall to install a non stock heater and it looks like he used a cold chisel to enlarge the holes. A couple of years back, I applied a patch over the carnage, attached with pop rivets temporarily hiding the previous sins of the past. This was done to improve the appearance after I rebuilt my engine, with the intent of restoring the firewall back to stock, when I addressed all of the rust issues with the cab.

To minimize the butt weld joint, I removed the section of firewall that was spot welded behind the upper cowl so my patch could go behind the cowl like the original firewall. It came out really good. If I apply a spot of Bondo over the butt welded seam, you would never know it was replaced.

Edit: Added the bondo and a bit of paint. Very happy with the results.
