Best bet is to find or download a factory shop (Helm) manual -- that'll have the most detailed, illustrated instructions available. There are lots of places advertising free manual downloads, but make sure that what you're getting looks something like this:

Frankly, it's worth it even to buy a copy -- $46.50 from the original publisher, Helm, Inc -- because it's the best documentation you'll ever have for the car.
Unfortunately, my reference copy is the 1990 version, which doesn't have any of the B21-unique specs.
