It has a strap built on, but I think the pickup could still rotate down a little.
Im thinking the previous Milodon pickup rotated down, contacted the pan, and then the vibration/contact broke it off.
This is the "extreme duty" pickup that was recommended:

I had a 18314 on prior. Identical except for the gussett that they added.
