Nice thing about Class C's (at least Ford-based ones) is that pretty much any auto parts store will have pads. I had a caliper lock up in a small town and the parts store had Pads, Calipers, and Hoses on hand.
If Bryan says those NAPA pads are the good ones, then that's what to get. His suggestions are always solid.
But let me mention, I went with another of Bryan's suggestions and replaced our entire front axle assembly (same as yours) with a late model takeoff assembly. Key time to do it would be if your Rotors, Ball Joints, or other major parts need replacement. All our stuff was OK. I'd in fact done a full front brake job and still have those good parts. I did the swap to improve capacity, braking, and handling. All of that worked out and I'm glad I did it.
