In a worst case scenario and I couldn't find the front dolly and had to make one how important is the leaning wheel feature? I don't have any experience using this type of grader so this will be a learning project too. I was thinking if I had to I'd build a long drawbar fixed to an axle with a sort of gooseneck ball on it. And build an adapter for the grader that could attach to the gooseneck ball. Or as oldbeek suggested make a pintle adapter. I know... Thats blasphemy... But better than letting the scrap man get it.

Of course I'd much rather find the proper dolly.

For what it is worth, I had an Adams #8 Leaning Wheel grader and it made a heck of a difference to be able to lean the wheels if it was moving much dirt. If one is merely touching up a driveway the leaning feature is not so much. Here is a video of the legendary Squatch using an old Adams Leaning Wheel Road King.

Thanks for the input fellas!I wanted to update this since we all love a good story, and of course pictures.
Since the grader was only about a half mile as the crow flies from my house I decided to lift the front and pull it backwards with my loader all the way home. I set out with my 12v air compressor and aired up the tires. They actually held air pretty well. I then cranked the blade lift up and held the lift wheels in place with a ratchet strap.I got permission from a neighbor to cut across his property to drag it home. This saved me from having to go along the side of the highway and about a half mile less driving distance. With the help of my friend Luke, we lifted the front with my IH 510 Payloader and slowly backed all the way home. Fairly uneventfully. 
 

After getting it home Luke's son noted it was like a pirate ship, referring the the big wheels and cranks. lol
 

Still no luck locating the front axle, I think it may have got scrapped last time she cleaned up the property. Although I was happy to save the rest from the scrapper I have since found a Galion 503 that I am trying to get bought that would be more useful. So if any of you CAT guys are interested and willing to come pick it up in southern New Mexico I would love for someone else to enjoy it. Besides the scrapper. You rust belt guys would love this desert iron! lol

Thank you Neil! The Payloader has been some of the best money I ever spent! I like the cab on front when going forward, but backing up you never know where the back half is if you don't look. Been a problem a few times. lol.

I may fab up something to get by if I need it before I can get the Galion bought.
