Ron, that 10 bolt is an AMC 15, not a 20 as what came with the car originally. It is easy to pop in a 15 from a Jav cause the PO might have done that. The covers do not interchange, though. Two thoughts; Recount the bolts, maybe taking out one bolt to mark your starting point. Or, maybe it is Chryco cover, I believe the 8 3/4 inch fits but I do not know if the cover has a plug or not. Maybe an aftermarket cover. All 15s have plugs, that is the easiest way to tell them apart......Russ _______________________________ Do you Yahoo!?
