how do I cut my fleetside bed apart?

[passthebuck]

I'm in the process of disassembling a bed I'm using for parts & I was wondering the details. its top-down right now & all thats sticking out of the snow is the very bottom. All the cross pieces & bolts are visible on the bottom & I dug the front of the bed out so I can cut those bolts off. I cut off ALL of the bolts I could get at on the bottom & I'll do the front tommorow BUT I heard that there are some welds that I gotta cut at the back of the bed & I think there are some bolts holding the wheel tubs onto the bedsides. What else to I have to do to get the bed apart? where are these welds & can I get them the way the bed is now? I cant wait till spring cause it''ll be a mud hole in the backyard till june & I dont wanna wait that long! Thanks!
