I have some 24" stands you can borrow Colby, and I've got two things of wood cribbing I made that are 12" tall so that I could remove the rear axle with the 40s still on there.
In my experience from chaining the frame to my jack to check bump clearance, the frame near the gas tank is kind of a pain to get a chain to wrap around nicely. In the past, I have put the axle on jackstands, removed tires, lifted axle, removed jackstands and placed them under the frame, and then lowered the whole thing on to the jackstands. To get the axle out because I have so much droop, I then (the jack has been under the diff this whole time) placed a jackstand under each overload as close to the center pin as possible. The stands under the overloads really weren't supporting much weight, and the ones under the frame had a lot of weight on them so it was pretty solid.
Way easier with the cribbing though, I just bought like $25 worth of 2x4 and stacked them with some good deck screws. I made the base several inches wider than my stands, so they're actually a lot more stable at 24" with the cribbing than the jackstand fully extended at 24".
