Are you kidding me! Phoenix is about 3 million people, there isn’t a junk yard with a D44 for sale? The ring and pinion and master install kit cost $400, if you can get someone to do it for $800 that’s $400 labor, not that much if they know what they’re doing, I’d just have it done. A D35 is a step backwards, I wouldn’t recommend it. Have you been to a wrecking yard and had them look for an axle for you in their computer? They have access to a lot of sources.
