Title: Another cab swap question
Post by: 73resto on March 03, 2008, 09:25:58 pm
Swapping cab and front clip from 73 1/2t auto (no ac) to 74 1/2t auto w/ac, read alot about picking cab up and walking it off but not much on what to disconnect. Please direct to a previous thread. Took beds off, ready to take hood, fenders, core, Read in Haynes take out column. Do you have to take off brake booster or just unhook brake lines? Disconnect gauges from back of panel? Cab with ac has something extra to be disconnected? Fuse block? Pedals? Thanks for responding

Questions I ask you is what are you using, if anything, from the cab you are taking off?

If it were me and just taking the cab off the frame...

E-Brake, speedometer cable, steering shaft from the column to the box, take loose the brake master cylinder and support it if the brake lines are in good shape and the brakes work well.(then you won't have to bleed them).  Disconnect the wiring harness to the engine bay and the brake/tail lights, gas tank wiring and Heater hoses/AC lines.  Easier to have the doors off but not neccessary.  Unbolt the cab and 4 guys can take it off.  If the bed is still on it, use a long 4x4 and center the boom off an engine hoist.  I have done it a bunch of times.  It takes a few tries to get the hoist in the right spot to pick it up straight.  I think that about covers it but please if I have missed anything please chime in.

I used 4 people, a boy and a small farm animal to move mine :D

It is ALOT lighter without the doors and interior.

I used my forklifts when I took mine off and put it back.

I took the interior out and doors off my 84 gmc and used a cherry picker with a block of wood inside the cab and me and my wife took it off ourselves without incident, just be aware if you do it this way the firewall will want to droop down.
