I'm not a mechanic but....
If you're going to try and save the cloth, you'll want something to pull the staples. If not, then bring a razor to cut the cloth off. Pull the staples later on. A flat head screw driver with a thin sharp point works too.
When I took apart my GCIII, I used a rubber mallet to separate the ends of the frame from the sides of the frame because they were really tight. Not sure if the older ones are like that. You could use a regular hammer and bring a piece of wood to use as a pounding block to not damage the frame. If you have a friend and a box truck, you could just carry the frame out intact. It won't be light, but neither are the slates. lol.
Bring a nice solid container with a good lid of decent size. There are a lot of bolts, washers, screws of varying sizes. Real easy to lose a couple. While not difficult to replace, it is an inconvenience.
