Compellent CHA 1 Z Track Cache Card WTB

We have two EOL and non-service-contracted Compellent CT-SC020 that has "CHA 1 Z Track Cache Cards" that show status as "Expired".

Write caching is disabled when I go into Properties of Volumes. We're only using the Compellent as non-critical development server storage at this time but I can imagine the performance isn't what it used to be with the write cache disabled. It's still a solid 24TB of storage so I'm not willing to just junk it quite yet.

Question is, any one know where I can get new or non-expired Cache cards for our compellent? Or even force the Compellent to think the cache card isn't expired?
