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. Anyone know anything about this or better yet have one laying around they could sell and ship priority mail on my dime?
Thanks
