2000 Mustang V6 studs/lug nuts....

I sold the silver eclipse that's pictured below and want to put the wheels from that picture on my girlfriend's mustang...

The pattern fit but the lug nuts are too small to thread onto the studs of her car. What size are the studs???

I'm gonna need really small lug nuts of that size in order to fit in the holes of the wheel, does anyone know where I can find lug nuts like that??

Thanks.

anyone?

I got mine on eBay.
