17" Bullit center caps

I know it been discussed has anyone found a proper solution to the center cap issue in running bullit rims on A body. I have the Dr Diff 13" front brake kit and Dr Diff 11.65 rear kit. Rears are easy just any push in cap works its the fronts that are the problem. The dust cap is nearly flush with the outside of the rim center. Need a push in cap that is domed to clear the dust cap.
Thanks
