info on conversion lugnuts needed to fit newer wheels on old truck

[cleansquare]

Guys, it seems i didnt research enough. Im installing these newer hd wheels on my truck, i knkw i need the lugnuts that have the external thread for the center cap.

I rhought the lugnuts that came with the wheels would work, and although the inner threads look thr same as the lugnuts that came off my truxk, tbey dont thread easily. I had to force one and pulled it off thinking it must be a different thread.

Can anyone tell me EXACTLY what i need to run these wheels? Will the factory lugnuta that came with these wheels not work on my older studs? If not, what are the exact dimensiona i need to buy? I want to try and find them local if possible. Thanks!
