97- 04 mustang rims again !

One possibility might be, and once again I stress mighty be, a Mr gasket flat end chrome dust cap. I think the Chrysler cap measures 1.78", and the Mr Gasket is 1.79. Maybe you could take a Dremel cutting disc make a small relief, and than pop it on. It's not a great idea though, if your putting you bearing at risk. Plus chrome plating like that always rusts.
