Need help finding a particular Lug Nut ?

[Kram]

I upgraded my old 93 Rangers stock 14" rims to just some stock 15" rims off a 2000 Ranger Splash problem I'm having is they didn't come with any lug nuts now I'm having trouble finding the right nuts that go with it. The lug threads on my wheels are 1/2" but the head of the old lugs nuts are just to small to hold the center caps on. I been around to most all the local auto parts stores and they don't have anything that works to fit it ?

Can someone please tell me what particular size or part number lug nut i need ?

Below are the rims I upgraded to. Thanks

Look at Dorman part numbers 611199 or 611171. One of them should work.
