Lugnut Measurements? Help!!

Hi guys.. this may sound stupid to a few of you but i get confused when shopping for tires sometimes.. especially when using thie tire.com thing off this forum.. I look up rims for my car. 1988 chevy camaro rs I see some nice rims. I look for some rims for my girlsfriends car, which is a 2000 ford mustang and i see the exact same rims. Model number, measurements and everything. Usually i know that when looking for rims. There usually is a catagory for 82-92 camaro's and than 93-2002 catagory for camaro's but when i search them on tirerack.com, I see the same rims for both an 88 and a 93 camaro. So the quesiton is.. will the 93-2002 rims fit my car? and does anyone know the lugnut measurements on a 1988 camaro? im confused here. help me out!

Go and get yourself a Jeg's, or Summit magaziene, look in the rums section, it tells you how to measure them.

i think your bolt circle is 4.75". Just because you see the same size rims on other makes doesn't mean the bolt circles are the same.
