Stop in for a cup of coffee

An old school way to do this is fine sand. Put sand in drum and turn adjuster to allow some clearance. Run car on stands and apply brakes or just apply parking brakes several times. Mates the shoes up nice. Take drum off clean up mess adjust and good to go...
Good luck finding a shop with one of these today. PSA paper on the drum surface and turn it and adjust as you go will mate them to the drum.
