Here are some pics of the frame backhalf, everything isn't finish welded quite yet, and I don't have the fish plates on right now, but I figured I was at a point where I could post some pics.
This is the angle I had to cut on all the pieces.
and then I tacked in the pieces, and rolled the rear axle underneath and tacked it in place as to minimize any warping while welding, and welded up the joints I could get to.
and then took the body off for finish welding.
next comes the fish plating..
