I f'in hate drums with a passion, so I say YES. You should be able to pick up a rear 35 cheap, and calipers and rotors are really cheap as well.
You may even be able to convert your current rear to disks with boneyard parts (backing plates and caliper brackets, I'd go new with rotors, pads, and calipers). Not sure if the axle ends are the same though, you might want to check that out.
Before you install it, go through the parking brake and add all new shoes and hardware, especially the two peice actuator that sticks through the backing plate. They rust up and the parking brake doesn't work. Mine hasn't worked in years, it makes getting an inspection sticker a bit tricky.
