Hey Tony, kudos to you for tackling a full on restoration, and admitting you had never changed brakes before. Some of us guys take for granted mechanical or electrical knowledge of a vehicle or.....whatever your interests may be?? The knowledge and willingness to share is what makes this a great site, and it open to anyone who asks, no matter the skill level.

So you rear is what is called an open differential, meaning that only one wheel pulls at a given time. Limited slip GM diffs typically have a clutch pack oriented in the side of the carrier, and a small set of springs visible in the carrier window. Some versions from different years or makes vary in appearance. All open diffs that I have seen are virtually identical and look like yours
