not sure on the particulars of your truck, but what's involved is,
- disconnect all wiring
- disconnect all linkage (tranny, throttle, clutch, brakes etc....)
- unbolt the cab.
- if the doors are on and closed, no bracing should be required, if doors are off, then bracing might be needed. if it's a good solid cab, i wouldn't worry to much about it. I've removed old ford cabs without doors or bracing, and they stayed straight.
- pick that heavy mutha up.
it is possible i forgot something, if i did, someone will let me and you know.....
