Just a thought. Find out how long the exact type of brakes you have ran, and head to the wrecking yard. Take both whole backing plates home with you, in case anything else is missing, and you can use the assembled piece as a reference. I'd be surprised if the 59 brake style didn't run a few years before and after.
The time spent cleaning the parts will be a good reminder about not tossing ANYTHING until your parts are reassembled.
Good luck....We're counting on you...
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
