More info

These are "new-old-stock" springs and will need to be cleaned (lighter fluid works well) before installation.  These are getting hard to find and I have a very limited supply with no guarantee that I will be able to replenish them when gone.  I highly recommend that you purchase the one you need now if I have it in stock
