Luis,
Welcome to the bolt. The 86 may not provide you with many resources for your project as the rear end is considered too wide for the AD trucks and the front suspension does not lend itself to a straight forward transplant. The drivetrain though would be a good option even with all the electronics that go with it. The swap will not be easy but if you wanted easy you could go buy something else. Even the 2000 rear end you say you have installed may pose some fender clearance issues so you may want to check that before you go much further.
