here we go. $68.4 for a pair of H&R wheel spacers and about $29 for 10 wheel nuts. total is about $98. It does not matter how many miles you have your wheel spacers on as long as they are used. You have no way to get more than $80 from others. And I won't even offer more than $65 for your used one. Good luck man.
