Could some one be able to post a pic of what the original rims looked like on a gtcs mine has some nasty covers and i want to get originals or something like them?

here's another page from the Mustang Recognition guide book.

Chamberlin,
You could have any style of wheels on the CS, unless you got the GT option then you got the argent slotted wheels, however, most upgraded to the chrome slotted wheels for their GT's. And you had the chrome wheel cover that went with the slotted wheels with a GT on the top if you had the GT option. But most CS's where not GT's so you could have any wheel option you wanted without the GT letters.

Regarding the rim issue, you might want to know that the spare tire rim was the same as the your standard rim, unless of course you had the space saver spare.
