8 1/4 bearing adjuster

Long story short...it's broke and I need a replacement. The Yukon gear part number is YSPSA002 or US bearing #33527. I've been looking for over a week and this part is out of stock or backordered everywhere.
The specs say it is for a 7.25/8.25, now I have a 7 1/4 under a running car this is in line for some modifications later in the year. If this part will work I'm willing to take it apart and use it. Looking at the 7 1/4 though is looks from the outside it won't as the axel tubes are 2 9/16" as opposed to 3 1/8" on the 8.25. My other option is to go to the Pic and Pull and get it out of a Jeep, Durango, Dakota or Ram that option though is not really appealing as who wants to be laying in greasy, wet dirt in some junkyard. The only upside to that is I might be able to find a rear disc brake setup for my 70 Duster where this malfunction is currently happening.
Thanks

I have a Big bolt pattern 7 1/4 rear apart. And might have a small bolt pattern 7 1/4 adjuster on the shelf. Measure the diameter & the size of the hex of your adjuster, and I can measure mine. At least that way we can see if the 7 1/4 part will work.
