Questions about lifting my 1972 short box?

[donelan07]

I purchased a 1972 short box not to long ago and was planning on putting a 3 inch suspension lift kit in. Does anyone have a preference for a kit? What will I all need to know about putting a lift kit in? The frame is rusted out over the rear wheel on the drivers side so over christmas break I will have to disasemble the truck down to the frame and I thought it would be a good time to do the lift.
