You nailed it though. I did not verify the pistons are fully retracted. I assumed they were as they have never been used, but we know how that works. I'll double-check that.

The SSBC kit does show promise. It lists a 10 1/2" rotor, while I am dealing with 10" ones, but that is close enough for the same caliper to be used. I'll look into that one. THANK YOU! Keeping my fingers crossed. I did note those pads look a lot like the Thunderbird pads I just tried.

By the way, I did research the numbers on the castings and came up with a blank.

You've probably sorted this out already, but calipers with integral parking brakes need to be rotated while being pushed back in order to retract them without damaging the parking brake mechanism. I discovered that when I bought a disc brake conversion kit with GM calipers for my car. When I got it I worked the parking brake actuation lever on the caliper a couple of times before installing it, then had to deal with how to retract the pistons in order to actually install the things. There were no instructions in the kit on how to actually do that and, not being a 'GM guy', I needed help from the Internet to figure it out.

I bought a kit from Amazon that fits most makes and models. Money well spent, though you may well be able to borrow or rent one from many parts stores - especially if you're buying brake pads.
