Best car cover you use for your mopar?

Look at California Car covers. They have several versions of soft outdoor covers that offer good dust protection for a reasonable price. You don't need mirror pockets or added room for the Go Wing. I have a California Car cover on my 71 Challenger conv that has Rallye mirrors and a Go Wing and it fits just fine without the added pockets. I copied the link to 71 Duster covers, so hopefully that is what comes up. Good luck.
