7, 8 and 9K Kodiak Calipers ALL use the same pad from the late 80's Buick Century HD. Always buy SemiMetallic pads best quality available. This is per Kevin at Kodiak.
Be sure to use blue Loctite and use the proper silicone grease on the slide bolts and all metal contact points. The allen wrench can be used to properly tighten the slide bolts just slip an open end wrench over the allen for a "cheater".
