Don - looking great as always.

Can I make a suggestion without getting slapped silly? At your frame rear kick ups - add a triangular gusset inside, under the body as well as above your new mounts. They only have to be 2-3 inches, max, on the weld side, but will 'triangulate' the chassis under acceleration loads particularly. Myself, I would probably fish plate it inside, but that's my tendency to use 5 nails when two will hold a piece of wood
