Here is the generic info packet from the GM Heritage Center collection for an '82 Full size pickup:

That should give you an overview of what options were available, by RPO code and name.
If you are super interested you can send your VIN and $50 and the Heritage Center will return your original invoice, complete with dealer info, build and shipping dates, RPO content and pricing.
