Carpart is the web site I used to locate my volt pack out of a salvage yard. Unfortunately, they call it a battery. Limiting your search for Volt models cuts that down a lot. A lot of the salvage places don't know that the drive pack is a different thing, it's just a battery to them.
Back then you could get a pack for $500, but with the solar people sucking up anything storage, that avenue is dead. The packs are still cheaper than reman and you can sell your left over modules to recover some cost. If you find a prospect, act fast because it wont last long.
Most salvage places will warranty the battery as functional for some time frame, but it is yard specific.. however since the modules generally interchange you could assemble a Frankenstein pack very easily using the best of both packs. Since we're commenting about Frankenstein, there used to be places that would sell used verified good modules on the web.
Have you thought about bottom balancing the pack? 5-6 years ago that was the rage for getting more life out of a pack.
I can't help more, my pack is now 10 years old, no BMS, and most cells are within .02 volts charged using a fluke dvm.
