Details:

This will also fit the F-134 Willys engine. This is a nice original crank pulley from Willys L-134. I m pointing to it but would never affect the belt as its dinged outside. It has one tiny ding you can see in the pics.

The seal surface has a tiny groove in it but my personal jeep way worse and its sealed up perfect.
