@JR_1979 , when I ordered rear discs on my VS, they installed an EMPI set, which look a lot like the picture of the caliper you posted (although mine are 4-bolt wheels):
I replaced pads a few years back and discovered they take a very common pad that was used on a lot of cars around 25 years ago (including Ford Tauruses). The industry term for this size is D610.
I ordered a set of Bendix ceramic pads from Amazon and they were the right size for the caliper. But they were a little too thick. I couldn't spread the caliper far apart enough for the pads to drop in around the disc, so I ended up having to sand about 1/8" off each pad. After that, they've worked great:
Despite how it looks in this photo, they're just about 3 and 5/8" wide:
Here's the link to the pads on Amazon, but any auto parts store should have something in that size.
