A couple of quick questions.

1. I noticed the tiniest little tear in one of the ball joint boots. When it's just sitting there, it's practically invisible, and I don't think it goes through the whole thickness of the boot. If I push on it a little, you can see a tiny (less than 1mm) surface tear. I'm assuming that's probably okay? See pic.

2. There are two extra metal spacers that came in the bag with the castle nuts and cotter pins. They seem familiar from the build school, but I've looked ahead and can't find them called out in the manual. Anyone know what they're for (see pic).

3. I remember at some point early on, there are a set of parts that are specifically labeled right and left, but I'm supposed to swap them because they're labeled like that for the hot rod only. Can someone let me know which parts those are so it's fresh in my mind?

Thank you!
