These are the Klingon Bird of Prey ships that I have been doing for myself and a couple of friends for awhile now. Due to mounting requirements, these are only intended for the Premium/LE models.
These stay on the entire time the game is powered up, just like the Enterprise and the Vengeance ship! They really balance out the playfield and hide the VUK mechanism very well!
Price is $65, shipped. Plug and play installation and simple mounting using existing posts. No modifications to the game are needed.
PM me if interested.
