Have you checked the manufacturers website?
Brakes and Components

PA does have a good return policy.

Good eye. Interested as well. I don't have drums or wires on our 1977 just a square plate on the axle housing with 2 holes. Not like I need an excuse to spend more $ right now but brakes I feel would be a worthy mod sooner than later. David can you please let us know if these will work on a stock axle? Dumb question but where would you source correct drums?

You can assume they will work with the part I was asking about, since they are the same brand.

Lazy alert sorry.
But thanks again! Looks like a trip to PA. Are you going to get some also?
Will post more Qs on separate thread.

The brakes on the trailer that I was going to put these on have never been hooked up. There was never a magnet. How that happened is beyond me. Since they are basically brand new, I am just going to find the correct magnet. I have a couple of 1300's that have the square plate, but no brakes. I think smaller brakes would make more sense. Princess Auto only sells 3500#, and larger, brake assemblies. I think I will get the brakes from a different supplier.

Are your drums 10 X 2-1/4"? If so, yes!

[David Tilston]

Is the 2-1/4" the depth of the drum?

It seems to me drums are usually a bit wider than the shoes. If the drum is 10" diameter and a bit over 2-1/4". that's probably it. I think most all 10" drums nowadays take 2-14" shoes.
