Those are disk hubs, they made two types of hubs disk and spoke, the person ordering had to choose. The spoke adaptors I talked about were a "spider" (spokes) that bolted onto that hub with the lugnuts you have and than the spoke rim attached to the spider in the normal way for spokes. I've seen some at ATHS truck shows, and pictures of course, but they were rare, not the least of why was because who ever ordered the truck had their choice, so why would they change their mind?
I have one K-7 on spokes and the other on disk. If I had my choice they would both be spoke, but I'm not about to change something that functions good enough for my use.
I measured the one K that sits on 9.00x 20 rubber and it has 6" rims, you might get 6.5" on there but I would have to try to be sure.
