This is for the F350 version... '53 to '66. Maybe this isn't appropriate for your F4 because you said five lug. I didn't see how to post a photo on a pm. But if you want to convert to an 8 lug modern rim, this is what I did. I cut off my six lug F350 flange with an angle grinder. I had the hub spinning from an electric motor from an old bandsaw as seen in the photo. Cut with a cutoff wheel on a 10" angle grinder. Used a 'toledo adapter' from wheeladapters.com. It bolts to the 8 bolt on 6.5 pattern that holds the brake drum, after you get rid of the old school 6 lug flange. This should be done by a machine shop, but mine came out fine. 65 mph, no vibrations down the road like a magic carpet ride. Anyways here's a couple of pictures of what some say isn't possible. I later welded the remainder of the hub to the toledo adapter, JIC.

 

Many thanks for this information. My hub to wheel is five lug as well as the hub to brake drum is five bolt. Wheeladaptor web site says they don't do different bolt pattern adapter but they contradict themselves with a new offering of eight to ten. I will contact them about making such five to eight lug adapter if I run out of options. I am trying to determine if a later hub may fit the spindle of my F4. Homemade, Garry has a conversion to eight lug on his new hauler and is trying to determine what was incorporated in the change. He said it looks like some kind of adapter, spacer.
This eight bolt wheel change is something I would like to do but I do have the Firestone wheels on the truck now that I can and will run. Going eight lug all around would be much better.
Thanks again, Rep points given.

Here's a picture for others who start with six lug. Somewhere there is an 8 lug hub that fits your 5 lug setup....

 

Ray, this looks like the adapter on my 49 hauler, mine doesn't look quite as deep as these but may be, still haven't been to the garage, Garry

Dragging this old post back into the spotlight because I’d like to know what the story on that 8 to 8 lug adapter is! Bought or built? I get some of the machining you had done but curious if there’s a few other pics or anything. I wanna do the same to my 53 to be rid of the 6 lug pattern but want to retain the dually wheel look.

 

Can you do the same thing and use a 1989 drum on the outside of the spacer, to make the drum eseiar to replace.
