Working with the “new” parts that are available today can be a real challenge. I just ran across some front VW Beetle brake drums that were way out of tolerance. After putting new bearings in I installed the drums and the axle nut bottomed out on the threads before the bearings got tight. Then on the dust caps, the left side the cap wouldn’t even go on, and the right side the cap was too big. Needless to say I sent those back to the parts house. It’s bad when you wait 4 days for parts and then they don’t fit. That holds up production.
