Hmmm. I'm confused. The "build" itself looks OK, what the pictures show, anyway. Metal splits are caused by the body moving going down the road. The only thing I can think of it that the body bolts are not secure to the frame. Altho both of my Land Commanders were made like tanks...
Pictures of the damage would really help.
Worst case scenario:
This photo looks like a few of the restorations I have seen on Facebook.. lol... Except for the pink dog.. but I guess he didn't make it. Sorry for the dark humour .. I haven't had my morning coffee yet..
