OEM 16x6.5 6 lugs for my 89 found...now the questions

[n2xlr8n]

I've researched the info I could find here, but..

I have a stock suspension 1989 K1500 and I wanted the original wheel (N67) the truck came with-
Found a OEM set today (deal of a lifetime, really- $75 with beauty rings), but I'm having trouble making sense of:

-Which center cap fit my wheels? The cap with Black lugs or the silver Allen head-looking (my preference)?
- Do I need special lug nuts for the center cap to mount on the wheel?

My intention is to mount 235/85/16 K02s or Wildpeak A/T4Ws on these wheels, but I'd really like opinions from those that have seen it / done it from a size and aesthetics POV.

Thanks so much for your help.

Kind regards,

Steve

Big thanks to @JS45 ...He straightened me out on the center caps and lug nuts required.

Went with Toyo Open Country A/T III in 235/85/16 (9.25 wide, 31.75 tall, 7-7/8 sidewall). I've had such great experiences with Toyos, so I stuck with that.
