pulling an engine

i want to pull the engine out of my 91 caprice, for a possible use later.

should i also pull the wire harness and computer? how much of the wire harness should i pull? fuse block, ECM, etc. (should i leave them connected?)

what about the rear end--should that be saved also. what other parts?

91 caprice 9c1 with all of the cop goodies. i'm thinking of just sending the body to the junk yard.

what do you think?

yes i would pull the wiring and computer, its makes it alot easier if you want to use it later, instead of tracking down a new one. for the rear end, it depends on what gearing it is and whether its a posi or not, if you post a pic of your SPID service parts identification, i can tell you
