Hi Craig!
What you are looking for is the etrailer Electric Trailer Brakes - Self-Adjusting - 12" - Left/Right Hand - 5.2K to 7K # AKEBRK-7-SA. As you are needing 2 rights and 2 lefts, you will need to get two sets of the # AKEBRK-7-SA, but it is self adjusting and works for 5,200 to 7,00 pound axles (12" x 2").
I do have to say these do not include mounting hardware though, so if your hardware is looking a little worse for wear, you will want to replace it. We that is the Mounting Bolts and Hardware for 12" Brake Assemblies # BRKH12, but again, you will need to get two sets of this as it will only cover one axle.
What kind of trailer are you needing these for?

I could use my old mounting bolts so that was not an issue. Putting them on was not hard but getting the self adjusting brakes initial setting proved challenging. I found it very difficult to adjust through the slot and ended up making an adjustment with the drum off and then putting it on to get the correct amount of drag. It was trial and error but it worked. The self adjusting mechanism makes it difficult to adjust them through the slot. I am sure that someone doing it all the time can do it successfully but I never mastered the trick.
