OK I see the split outer ring on the one. Good news for the truck's owner, he doesn't have to buy all new wheels, as I just did on mine that had the widow makers. The downside of 22.5" drop center wheels is it's just about impossible to mount one up yourself. I bought the special tool and tried my best.. nope.
I've broken down and put back the ole' widow makers on my own, on several occasions. Last time, I used a bulldozer blade as the safety cage as I was on my Grandma's farm.
