Everybody do yourselves a favor. Before you run into BIG trouble like I have on more than one occasion, swap ALL those POS's out for McGard lug nuts. They are solid, one piece lug nuts and they're guaranteed for life. Plus they look nice! The part number you need is 64010. They're pricey, but well worth it when you're on the side of the road trying change a flat, you don't have to worry about stripping that skin off of your lug nut and getting hopelessly stuck in the wrench, or having it spin on the nut or strip with no way of getting it off! It's cheap insurance if you ask me. You WILL thank yourself. Not to mention, while your at it you can buy matching wheel locks if you have expensive rims. If you look at the wheel lock that's on your spare tire (from the factory) you'll see that it's made by McGard. Don't forget to properly torque 'em in increments (50 - 75 -100) up to 100 ft/lbs!

i have some missing on every wheel. no biggie for me they are just for looks

You need to know that without the covers your lug nuts are 18mm instead of 19mm. Hope you carry an 18mm socket in your KJ because with the 19mm OEM tire iron you can forget about it.

The part number you need is 64010.

Summit has them for exactly the same price - $12.99/set of 4 that I paid at Pep Boys and I didn't have to pay shipping.

On a side note, I wouldn't recommend the open-faced nuts, especially if you're an off-roader or live in a community that salts the roads in the winter. The open-faced ones will collect a whole behind-load of road debris and crud making life miserable if you have to do an on-the-side-of-the-road repair. All that stuff will collect inside the nut, and could possibly ruin your stud and possibly prevent the nuts from threading on and off properly. They're also weaker and more prone to warpage/breakage when you have to torque them, especially when the garage hits 'em with an air gun. I always recommend putting anti-seize grease on your lug nuts. Every time they come off, the studs get a fresh coat. I've never had a problem getting lug nuts off by hand when they are properly torqued and lubricated.
