...but one thing to make sure of is to make sure the shop doing the work has a large 3 bolt style drum puller so they can pull the rear drums. Those rear drums are on tapered axles and require a special puller to get them off. The typical modern shop may not have one large enough or at all. Older shops or those dealing in trucks may have a large enough puller but if the drums have not been off in years, be aware that may be a project in itself.
