It looks like the previous owner had a hell of a hard time finding a good place to drill the hole for his caster camber plates. I'm about to put on some MM caster camber plates. How screwed am I? Or is this not a big deal?
Not a big deal at all. As long as you can get the studs through that are on the bottom plate, you'll be fine. Make sure you can slide them freely back and forth. Looks to me that you may have to drill more on the passenger side to get it to slide.
