77 > 86 GMC pw/pl swap?

[littlebubba]

Everything should swap over to the 86,with out much trouble. Take your time , mark the wires with tape etc. for windows/locks, when you remove. You think you are going to remember everything, but just good practice. Remove and replace or swap as the case may be. Should be a great truck when your done with all those options and a big block. One other piece of advice, don't get rid of the parts truck until you have every last piece, nut and bolt , wire , brackets, anything you need for your swap until your done if possible. Put stuff in ziplock bags and mark them. Take pictures if you have to, makes things easier down the road. And buy a GMC service manual for 86, there cheap on ebay.
