Lower strut CAM Bolt?

Yep, these are specialty bolts, I would go to a pick your part yard to find one or try ebay. If the bolts on rock auto don't look correct I would nut but them.

That vehicle comes without that adjustment available so you use the camber bolt kit. Your description sounds like they just used a smaller bolt to allow some adjustment. That isn't as secure because it provides no alignment in the bolts position and you only have the compression friction holding the parts in place. It also means it likely will need the camber bolts in order to adjust for whatever the earlier repair caused. If it were mine I would buy two of the camber kit bolts and replace the lower bolts with them, then take it in for an alignment check.

I make it a habit to install camber bolts on anything that gets new struts and mounts these days, been caught needing them due to wear and hidden damage as well as questionable manufacturing of replacement parts. With a factory fresh car that has never seen potholes, curbs, or train tracks having a non-adjustable suspension is okay. However, once it's been on the road and actually used, things can get interesting, and now it needs some adjustment so you don't get odd handling or tire wear.

Yes, There should be a couple of large "washers" with them that go over the slots and allow the bolts to work.

You are welcome.
