Removing a rear end

[ryans69chevy]

I'm going to an old farm to check out some rear ends for my 49 3100. I'm wondering what the best way to remove would be. I'm planning on taking the rear end, drive shaft, and the torque tube. I kinda have an idea of how I'm going to do it, but idk if there are any tricks or surprises. I'm mostly worried about supporting the frame for when the rear end comes off. Is wood sufficient enough? It's gonna have to be something that I can just leave out there, cuz I'm not buying the whole truck. Whatever I put under the frame, I need to put ahead of the rear wheels so when the rear end detaches from the frame I can just slide it back. Is this correct? And I suppose it would be safer to unbolt the driveshaft from the tranny first, so I wouldn't have to crawl under there when the frame is sitting on something other than the rear end.

Thanks for advice!
