Branchline Heavyweight coaches in CN and CP

Well, after fiddling with these two cars for the past week, trying to get them to run right, I've come to the conclusion that I won't be able to fix them. I ended up haveing to glue the roofs on because of the bowing. I even glued the styrene crossmembers and the roofs still wouldn't 'snap' into place like the instructions stated. And when I tried to run them on the layout, they consistently derailed on my 26" radius curve. I made the modification that Charlie suggested but that made no difference, the trucks still wouldn't rotate enough without hitting some of the underbody detail. I trimmed both the brake beams on the trucks and some of the brake rigging on the frame and still no go. 
   

All I can say is, anyone what them?
