I have here what may very well be a rare item for sale: Zenith Forge's ZF: 001 - Cretaceous Advancement Upgrade Set for Generations/FoC Voyager class Grimlock. Opened, yet still in mint condition. If there is anybody out there that still appreciates and owns a Generations/FoC Voyager class Grimlock, this upgrade set will be a great improvement. Total price is $40 ($30 + $10 for shipping).
