Well I squeezed in a little more progress. Last night I "integrated" the cab cowl and the firewall by adding 4 little tab brackets. (Metal for these brackets courtesy of leftover 67 pickup roof tin.) Here is a shot of one of these little brackets that contains my personal best MIG bead so far (on the right) I should have shot the photo before I primed because it was sweet - like a factory robot did it.

The effect of these 4 simple little brackets was dramatic. Suddenly the cab structure wasn't "loose" anymore as the firewall began to serve as a major structural support. Now I can grab onto the cab and it feels like a real truck.

I was having such a good time that I decided to see if the GMC HVAC unit was going to clear the cowl sidewalls and what do you know!!! Misses by a 1/16th or so! So here's a teaser pic with the HVAC unit mocked up and one of the dashboards thrown in for fun.
