Before you buy anything, determine what you need. The only way to do that is pull the drum and examine the shoes. First, examine the shoes for remaining pad material. They may only need adjustment.
If the shoes are worn that bad, pull one and take it to a shop that deals in trailers, especially utility trailers. They are better versed on repairing older brake systems and their prices are much more reasonable that RV shops. Many of those utility trailers on their lots use the same brake/hub/axle systems as on your Sunline. They can supply you with the size shoes for your brakes.
While you have drums pulled, it's time to check the bearings and seals. If they need replacement, the trailer shop will have what you need.
Repack the hubs, too. There are lube points in the brake mechanisms so lube them as well.
Check the magnets and wiring as well.
Put it all back together, replacing the cotter pin if needed. Adjust the brakes and you're set.
The Dexter axle manual is in the files area. Brakes and hubs are part of the axles. That manual will tell you all you need and more. The answer to any question about brakes, hubs, springs, and axles are in the manual. There are also reference charts on bearings and lubrication.
These are simple, old fashioned drum brakes. (My '99 had the exact same axles as your '89.) The only unique part is that they are activated by the magnet instead of a pull cable. They are very easy to work on in your driveway.
