Problem with 2000 z71 wheels on 1997 2dr

[97 2DR]

So I picked up some 2000 z71 tahoe wheels with some bfg all terrains for 300 bucks, went to put them on and the lugs have a different thread than what's on my tahoe. What size lug nuts do I need to get? My factory lugs say metric and looks like a - and then a 9.

I will post pics tomorrow for you guys but I wanna get some chrome acorn lugs and I don't know what size to get. Need y'all's expertise.

I have a 2000 z71 that came with wheels of a 96-99 4wd when I bought it. I just used the regular lug nuts in it as i cant see spending more money on just lug nuts. It took me about 2 years to locate a set of original wheels for this thing for a decent price, awesome find for you!
