Looks good. Nice work

 

Well yeah I know that. Just confirming is all.

He basically made the same adapters I have sitting in my basement

 

No, he could of.....

A. put the factory dually hub on then the 8 to 10 bolt adapter then the tire

OR

B. Had the 8 to 10 lug adapter machined big enough that he could of Just bolted that to a SRW axle then bolted the tire on

 

Here's what I think:
The Dana 60 is from a '99.5 - '04 Super Duty, which has a different lug pattern than the OBS.
Notice the adapters, the 10 lug pattern is smaller than the 8 holes that bolt it to the axle.
The OP used '99 - '04 Super Duty F-550 dually adapters (and Dana 60 axle) because they use a larger pattern 8 lug mount (220 mm?). I have a set here from a E-550 I am hanging onto for some reason, so that's what it looks like to me.
Then he had the 10 lug adapters made to fit the '99.5 - '04 550 dually adapters.
Just my opinion from the looks of the above pic.

Edit: Then again, there's no way those adapters would fit behind the F-450 wheel, so I'm back to scratching my head again...

 

In the photo, the OUTSIDE bolt pattern around the edge is how you bolt the Front plate, with the 10 lug pattern, to the Back plate, with the 8 lug pattern, together.

I know this because I have a set of these adapters in my basement lol

 

So the 10 bolt F-Super Duty lug pattern is actually that much smaller than the 8x6.5 OBS pattern?

 

The F-superduty is 10x7.25.

It's not much larger than the 8 lug trucks

 

I am really confused now.
The 10 lugs on the adapter are smaller than the 8 holes.
The 8 holes bolt in place on the oem hub.
So the 8 holes/lugs must be waaaay larger ring than 8x6.5??

 

Look at the RING/PLATE below the Top Ring/Plate

Those two rings/Plates get bolted together.

The BOTTOM plate has the 8x6.5 bolt pattern in it, with some of the bolt holes covered up. The holes are large so you can run a lug nut onto the studs with a socket.

The holes that run along the outside of the rings/plates are just for securing both plates together as ONE adapter then.

 

Here is my set, that is assembled.

These ones have studs in the back, that you can barely see.

 

Well dam, I had no idea thats what it was.
What a dumb way to do it.

 

It's the only way since the number of studs is more and the bolt spacing is so close

 

They should have just done 10 lug hubs and use the dually adapters like everything else. But then again, it's Ford so what do you expect...

 

Well. Ford didn't engineer any of this.

 

The F-Super Duty?
