One word of caution, the return springs for the Eaton rear are unavailable.
Remember this!
Fortunately they are plentiful on 1 1/2 tons and larger with single and two speed rear ends throughout the 60's in case one of your is broken. There are two different colors of springs depending on where they go on the rear brakes. Not that 50+ years of grime and brake dust makes them easy to tell apart...
