Pro Comp Series 52 center cap issue

[Pony Boy]

I mounted my Pro Comp series 52 wheels to my 2010 2wd Ranger yesterday, and I also tried to install my push-through center caps. On the rear wheels I had to use a 5/16 wheel spacer to clear the brake calipers, so my center caps are loose ( since the spacers push the wheel out from the hub, but the center cap is supposed to sit flush against the hub once the rim is torqued.) Has anyone else run into this problem with the center caps as well? Is there a fix?

An idea that comes to mind for that is to fabricate a shim out of something fairly thin (thick sheetmetal maybe) that has the 5 holes for the wheel studs, and a center hole (if needed to clear the axle hub) that is smaller diameter than your center cap.
When you put the shim over the wheel studs, the center cap will then rest up against the shim rather than it slipping down inside the spacer.
