for anyone that's swapped cabs on a Chevy truck, can it be done in a weekend? We're running out of warm weather here, but I want to attempt swapping cabs from my '78 to '73. The cab on my '73 is structurally compromised from the roll here's the plan- unbolt fenders, unbolt steering columns, take off doors, unbolt bodies, unhook heater cores and AC lines, wiring, etc., lift, and swap. How much does a cab with no doors weigh? Can four people and some 4x4's through the cab lift it? any advice?
