Moog camber kit junk?

When I removed the bolts, positioned the washer plates to where they should be seated on the shoulder of the bolt, they are 5/16 of an inch too narrow. Simply put, they are too short to work properly. In tightening them to be snug, it actually bent the eccentric when they pulled in. Simply incorrect application.

It would be really helpful for you to post pictures of the bolts so we could see what you're describing. A measurement from the eccentric under the head of the bolt out to the shoulder/flat area would also be helpful, as I'm sure there are plenty of us with OE bolts laying around that could be measured and compared.

I'm not saying the Moog bolts aren't junk, but that's not the only possible explanation. It's not uncommon at all for the suspension mounting points themselves to be bent, that actually happens quite a lot. And it wouldn't surprise me at all if every eccentric washer wasn't bottomed against the shoulder on the bolt when fully torqued, because that leaves you no tolerance from one car to another. If that eccentric bottoms out before the UCA mount has enough clamp force on it then the camber bolt will continue to move. It's happened before, and having the eccentric washer bottom out too soon is a much larger problem than not having it bottomed out.
