That looks like a bump body on a dent side frame. So that angled section really will meet up at the front when you cut and fit it? I didn't think it would. Anyone else with pics, please toss 'em in.
I'm trying to decide if I want to cut one of my lwb dent side frames, or do a massive amount of work and use a swb bump frame I got (it's still gonna be a '74 dent side body either way). I'm really at a fork in the road for this project. I have nearly every part I need in triplicate, Just missing a few odds and ends, then the assembly begins.
