Long Bed to Short Bed Q's

[Scamlee]

Hello everyone!! To start things off, I'm about half way through the rest-o-mod of a '71 C-10 long bed. I have the cab mounted to the frame and the motor all wired and plumbed. Just the other day, I decided to make it a short bed instead of long bed. I know that I have to take off the cab in order to cut the frame down and I was wondering what's the easiest way to take off the cab without disturbing the wiring and plumbing to the engine the least?
