I found dad,who is 70 years old,a rust free 56 down here in SC.He trailers it back to WIS.,pulls everything apart,and says he doesn't like the looks of a couple of dents in the roof He finds a donor back in the woods about 100 miles south of him and trailers it home.Then he cut the posts and welded the donor roof onto his cab.Looks like new.

He did this all by himself.I think he's a glutton for punishment but,I guess it can be done.
