Hey 90 Stomper:
I've been looking more and more at those moon discs.  I like 'em a lot.  Last night I went to a local guy that has been buying and selling wheels and hubcaps since the '60s hoping he might actually have a set of moon discs.  Dude takes one look at my wheel and says hubcaps wont fit on.  Now keep in mind he is old and half blind, so I didn't want to break his balls. ÂÂ
This morning I take a close look at the steel wheels on my '92 Sidekick and '03 Tracker.  The look identical.  Different style, but the same protruding lip and shape.
My question to you is did you have any problem fitting those moon discs?  Have they ever flown off your vehicle at speed and turned into flying saucers?  I really like the look of those discs, but I haven't had hubcaps on a car in years 'cause they never seem to stay put.  So please tell me about your experience with these things.
