Project Dukeshire

[cletis]

I have plans (dreams aspiration) of building a bagged 81 that sits on the rockers just to cruze in. Research says to; 3" Z, cut frame under cab, step notch over rear axle. My truck is a long box that I would like to shorten to short box status.
If I was to Z notch, Cut 2" or so off the bottom of the frame, shorten the frame, C notch the rear. All of these frame alteration make me want to box the frame for strength and piece of mind. My question is that with all of these mods would I be farther ahead to fabricate a complete frame out of 2x4? Has anyone done this? I don't think that my fab skills or knowledge are the variables.
Don't tell me I'm crazy tell me why I'm crazy?
Thank you for any/all time given.....
