Read the post and I had a thought that I haven't heard anyone mention. I've attached a pic that vaguely illustrates the welding technique I am considering. Not sure if it's a good idea, but it seems to eliminate what would appear to be a byproduct of welding around a single cross section of a subsection (frame-rail). The idea is to cut the new section at angles that will be welded along the 'rails' in such a way that no two welds are adjacent to each other, therefore the old metal does not have a single cross-section weld that creates an 'overheat' weak-spot.

Any questions?






The technique I used for the rear part was as follows:

Cut a 2x3" opening in the rear frame section. Slide in the subframe connector (easier than it sounds), and do a 360 degree weld at the opening (lap weld). Also want to have 4 or 6 holes in the rear subframe where the connector is stuffed and do some welds there too. Cant make the rear any stronger than that. As for the fron, it's just a typical butt weld. Couple gussets can't hurt.

See enclosed pic of rear on my 71 RR:
