well, it turns out the corner not fitting correctly was an alignment issue. WHEW, dodged that bullet!
Brian had the day off, so he was building this while I was trying to tweak the cab into the right shape.
All I ended up doing was tweaking my back though, UGH. Brian did an excellent job with the missing body panel though! We were kinda sweating that one, but it looks great! I think the a-pillar probably needs to come back 1/16'' by looking at the pic. I am just happy to have that corner figured out and that panel piece made, such a relief!
