Easiest way to remove 83 rearend?

[NastyNate32]

I don't have any experience working on leafspring rearends, just my 68 coil spring rear end. I doing a frame off resto of my 68 longbed and I bought a front end and rear end off my brother's 83 he is junking for $250. Only problem is, it is setting at the back of my dad's 10 acres. The front end is the same as taking off the one on my 68; I've done that. But whats the quickest way to get just the rear end? I'm going use my coil spring set up so I just need the rear end itself. Cordless saw-zall is a must I'm sure.

Can anyone give me some ideas what I'm getting myself in to or a quick way to drop it out of there?
