I'm swapping my 20's for a set of shelby gt500 take-off wheels i found on ebay.
Cheapest set i could find.

The lugnuts are not included. I've found aftermarket lugnuts on americanmuscle.com .
But they dont specify if they'll fit these rims.
Does anyone know where i can my the original lugnuts or aftermarkets that will work?

Are there any issues i can expect when replacing the wheels?

I reused the stock lugnuts plus the locking lugs from my 18" fanblades on my GT500's and they're fine. If I recall, I was told they're the same lugs as those that came with the GT500's.

Just about any brand will do as long as they are similar to the OEM ones.
