WTB: center caps

['89Z71]

I need a set of 4 caps that either snap on or have the single screw that holds them on. Ones from Eagle Alloy or American Racing should work, they need to be 6 5/8" outside diameter(give or take a 1/16). I would prefer smothies but will consider the ones with the hexagon shape on the center.
The type I need are like the center caps on the mid 90's chevys where the disk piece snaps into the center of the rim(the ones for stock chevy rims are too big though, I already tried them) Also if you follow the link to my truck in my sig the caps on those rims are the type im refering to.
I hope I'm not to confusing, and TIA
