Does anybody have a recommendation for 'shorter' center caps that'll make Mile Marker manual hubs sit flush instead of inset as they are with stock F250 caps? I'm running the stock polished aluminum wheel and stock center caps for ESOF vacuum hubs right now and the MM hubs are about 1" or so inset into the opening in the center cap. It looks like crap and debris/sludge/snow will get stuck in there making it a pain to get to the locking mechanism. Thanks for any ideas.
