I talked to both of the companies at Norwalk. It's interesting to note that they each have a very different way of performing the reline process. J & G mechanically attaches the liner to the aluminum drum with screws and then machines them off of course. Z & L glues them in with a special Locktite product. J & D have some of their drums actually out there racing in vintage road racing, (non-Pontiacs), Not sure if all or most of the ones Z & L have done just move the car off the trailer and on to the show field. If the used drums you have still have lots of original liner material, you may want to have them carefully machined, have a new set of shoes arched and give them a try. You never know, you may be one of the lucky ones with a good set. I have owned probably a 4 sets of 8 lugs and finally I have a nice set on a car. They are still original. If you decide to try and machine your existing drums, I recommend machining them with the steel wheels torqued to specs. while machining. It really makes a difference. Please post up what you decide to do.
