Very helpful information. Did you weld with weight of car on ramps or similar? I’m thinking of buying second set of ramps and put car on all 4 to eliminate concern of door alignment.
That question tends to open a can of worms around here. Everyone seems to have their idea on what's best. When I've installed subframes connectors, I put the jack stands under the front and rear subframes to take out some sag from the 50 yr old body, then put a jack under the k-member and take a little of the sag out of the front.
IMO, the main thing is you want to make sure the doors open and shut easily before you start welding. At the same time, some people weld them in on rotisseries with no problem, so who knows?? There's a lot of ways to skin a cat.
