Mancini Racing still selling Yukon axles that are 3/8"-1/2" too long

Backing plates and drums change according to the brake width. The axle length does not change

I don't have direct experience with them but when I spoke with Cass (Dr. Diff) he said the portion of the axle from the bearing to the splines don't change but from the bearing retainer plate to the drum flange does.
