Can't Find An Axle

I guess I just don't know enough about it. 8.25s are everywhere, but apparently this one is less common. It's a 27 spline, 32 5/8', 4.5" pattern. I can order one from Yukon, just thought the $400 tag seemed a little high. If anyone has a used one or knows if there's an alternative I'd be interested to hear about it.
