Kevinski - You may have already checked it out, but you can get a set of those pads from Bill's Truck Shop too. By the time you add costs for shipping and what not from Classic Parts, it may be cheaper to buy "Canadian" for you. Screen grab below comes from Bill's current PDF Catalog.

I should have looked closer/remembered your location before offering the original source. dang
