Finally after filling in what seemed like hole after hole, some factory, some PO, I started working on the making the firewall look as pretty as I could by filling in all the spot welds and little imperfections.
You can see where the heater box goes, it was pretty smashed up, I had planned on cutting out that peice from the 69 cab but it was rusted too badly, so I pulled, pried, banged, smashed, cussed a few times and finally got it pretty straight though the pic does not do what I did justice.
