The lug nut also fits so I'm going to order the rest of the set so that I can remove the adapters at some point. For now, I'll leave it alone because it works.
After that's done, I'll put the brakes back together and then take it in for alignment. I should have a solid 4 weeks where I can drive the car before a storage space is required for the winter months.
If I get real ambitious tonight, I'll pull the front end apart and see if I can get it dropped one spline AND put it back together. I like a good challenge.
