its standard on 5spd 82s, so its only as rare as 82s are, which are actually starting to be kind of rare. Yes the whole diff from your 82 will bolt to your 86, the question is what kind of shape is the diff on your 82 in? If its got over 200,000kms it might not be any better then the one on your 86. The 3.72 will give you great gas milage (on the highway at least) and make your car feel really slow around town. You'll have to swap the speedo gear on the tail shaft of your tranny too.
