Identifying disc pads

[AdeTuono]

Does anyone know of any resource that would help identify the original application of an unknown brake disc pad?

I've just managed to buy an old, used disc brake conversion kit for my '49 GMC, and would like to buy a new set of pads before I bolt it all up. There are no manufacturer's marks or numbers on the pads, or any of the brackets or discs. The seller wasn't able to give me a clue either. The kit parts are fairly obviously much more recent than '49. Here's the pad...

I've tried the Bendix app, but it doesn't help. Any alternatives?

Are the two pads different?

I think it looks like a GM D52 pad

Google image search?
