66 Valiant Vert RUSTORATION

The way I can see you doing this would be one of two ways first way would be cut up the 4 door into 3-5 major pieces,
1st cut the front frame, firewall, inner fenders and rad support as one piece.
2nd cut the main floor as another piece, now get rid the roof and rockers.
3rd you can deal with the back half in two ways 1st leave it in one piece or take the hind quarters off, leaving rear floor, trunk floor, rear frame and inner wheel wells as one piece.

Next take the vert to it basic unibody tie it together with tubing take just enough floor out to repair the rockers than put the new floor. Next put in the new front end, now the back half can be done in two ways first repair the hind quarters in and out with parts of the 4 door ones than install the complete rear floor and frames with the other one. 2nd seperate the back half from the car leaving the rear door jam tied in, weld on the complete 4 door rear section than graft the vert parts thets the way I'll go if doing it this way.
