I maybe getting some powder coating done and need to pick up 20 lug nuts that will work on the factory Nissan 06 ray wheels. The dealer wants $3.50 each, Is there a cheaper way to get these? Also does anyone provide a after market lug that is black and will work with these wheels? How about Nissan center caps? Any affordable way to get those? Also does anyone make a after market center cap for these wheels?

I am pretty new to all this but find this site very helpful.

Thanks
