I added more temporary bracing on the strut plates to get them exactly where they belong and rigid enough to stay there until all the parts were tacked in place. Once everything was tacked in, I checked them one last time. I had to make a minor adjustment on the right side and it was ready to weld. On this particular suspension system the upper mount is not adjustable. On most true strut cars, caster and camber are set by adjusting from the top. On this one, the upper control arm is mounted stationary and adjustments are done on the lower control arm and slotted mounting holes. This means that the upper mounting plates must be exactly where they belong. There's no adjusting them later.
Once I was satisfied that everything was where it is supposed to be I started welding it up, checking for movement as I went along. I welded areas on the left, then did the same areas on the right, moving back and forth to avoid the possibility of pulling everything off to one side. Still more welding to do up here but I'm closing in on it.
