Yukon Axles
No personal experience but every time I've seen them listed it says you have to use green bearings and B/E body brakes, backing plates/drums etc... A-body brakes are a different offset and Yukon axles are designed with the B/E body brake offset. I have only used green bearings once so I don't know if they make 2 different kinds but mine had the plate needed to bolt to the axle housing attached to the bearing.
