Congratulations on 20s man! I am using those little chrome lug nugs on my rims that most of the shops carry, I don't know how to describe em to you well, but they are open, not closed like the ones that the original wheels have. I had my rims on for a year now, and I removed em many times now, no problems with lug nuts at all, much better than the stock crap that the LSs come with.
Also, my rims have a separate wheel cap in the middle that closes the area where the nuts go, I don't know about the Fooses though.
I think any lug nuts but the stock ones will be just fine.
