wheel center caps

[immonacan]

Mine were just stolen off my 1500 "88 Suburban where I park in the city, by some dirty bastard. It is still a good lookin vehicle and I would like to replace them.
They are the 5 lug caps, and were held on by 3 cap bolts that screw into the rims. My question... Can I replace these center hubs with the ones I see that have the snap on lugs that snap over the wheel mounting lugs , and will thet fit my existing mounting lugs ? I wanted to check with this group, before I bid on a set on Ebay. The 5 lug caps with the 3 screw holes are hard to come by, and the bastard stole the screws also, of course. If someone has a source where they can be purchased used or new (set of 4 that has GMC logo) or any other advice, please post reply or email me....I Thank You in advance !
