Center Caps on 17" Steelies

I'm putting these 17x7 steelies on and was wondering if anyone had any suggestions for a possible centercap setup. I'm looking at the spyder bullet caps,or just running the trim ring and a set of chrome acorn lugs. The front would be like the rear except for a chrome grease cap. The rims are definetly hub centric and nothing will fit between the rim and hub. I thought of trying to get a set of rallye caps and trying to get them to fit. Thanks for any ideas.
