What did original wheels look like with 6.50x16x6 option on 71 GMC K1500

[Clanky]

Hello,
On my glove box sticker one of the options on the truck is 6.50x16x6 tires. I'm wanting to keep my '71 GMC K1500 original including whatever wheels might have come on it new. The truck has the 'custom' trim package. With the 16" tire option, does that mean it would have had steel wheels with hub caps? Like the smaller 'GMC' in the center hub caps either painted or chromed? Does anyone have a GMC equipped with original 16" wheels that I could see? I want to get original type wheels on my truck so I need to figure out what would be proper.
Thanks much!
