Hi,
You don't say where you are, but there are still brake shops around that will re-line your brake shoes with some old-fashioned rather soft linings. They will probably want the shoes and the backing plate, as well as the drum (or a measurement of the drum diameter). Maybe call around in your area and see who is willing to do the job - it shouldn't be too expensive.
New linings will be bonded to the shoes. You can glue and rivet your own, but it's not worth the hassle of finding the materials then doing a second-rate job.
