Wishbones are easy and fun, I don't get why people are making a fuss out of them. I found a ditch, and the front wishbone has buckled in the middle of the tube. My crappy amateur welds held fine. Getting the plate lasered and bent took more time than making the replacement wishbone. I had some spare bush tubes and a suspension bracket. I didn't make a full jig, just a 25x25 tube tacked onto a 3 mm sheet, with the bush tubes clamped onto it. The wishbone plate just sat on 10 mm spacers (M12 nuts probably) above the centreline marked on the jig plate.
