Wow, Wayne,, those are pretty nasty. I'm sure you might already know this but I figure I should mention it just in case. When you took the shoes off, there is a long one and short one. The shoes may be the same length but it's the friction surface I'm talking about. The shorter of the friction surface is the primary shoe, it always goes to the front of the wheel. The longer goes to the rear and is the secondary shoe. I would also get a new spring kit if your springs are rusty, they are cheap and if they fail,,the brake shoes will be quickly damaged. As far as brake shoes if you can and they are available, and you can afford them I would try and get the bonded/molded shoes or the rivited ones. They are much better quality and wont break apart from the heat like the rivted shoes. On your drums, there is a number cast into the sides of the drum,,it will say something like 10.500 this means that if measured and they are say 10.495 that you will only have .005 (Thousands), of material left before you reach the maximum Inside diameter of the drum. Unfortunately this is not enough material to remove to true the drums up and you will have to get new ones. maybe they have plenty of material left? Good luck Bro,, hope this helps. Slayer or Led Zepplin,(Dazed & Confused) should be on when you work on it.
