I put a set of 2000 2500 wheels on my 1999 K2500 and I can't find center caps that will fit correctly. I check the lug nuts and they are the same part number.
I have these wheels
And I have some of these center caps, lug nut covers won't reach threads on lug nut.
And one of these that I tried.
Seems like the lug nut cover is too short.
Wondering if I need caps like these....
