Don't really like the idea of repairing them if I'm honestMine were a lot worse than that and I had them repaired. I didn't want to loose the alignment and the rest was sound.
Suppose I could put the springs back on when I do it...Do them one at a time so you can check alignment with the one still on, and if you can pass a straight rod through the 4 spring mount holes things are pretty good.
Rest of the chassis is solid and I'll be welding it myself. I've got a Clarke 151 welder it .8 wire in it. Sounds like I need to get busy with the tape measureI missed that you already had them. My thoughts:
Think carefully about where you will make the joints to the chassis. You want to get to sound material and some people have started this job then found they needed a front crossmember so do some poking about and grinding before you commit.
Set it all up - you can use a laser level with it all on blocks and check and check again. Measure the diagonals. Do you plan to do the welding, take it to a fabricators, or get a mobile welder in? If you can get it all prepped and set up then a moble welder can be a good solution.
I was talking to a guy who paid a garage to fit a rear 1/4 chassis and it was out of line. The garage refunded a lot of the cost but that vehicle will never be right until it gets a new chassis.
