Chris is correct, the WW pad is not hard to get. Only that it requires you open your mind to some new suppliers! No, AZ won't have them...

The two most common pads in the industry are fit for these calipers; first is this one for many of the BAT and other DL caliper kits:

Available in a host of pad compounds to pick from and from many vendors.

Then there is the pad which I use, it to has the same properties of above with regard to supply:

Point being that supply is not a problem once you learn your way around.
