I have a Zex 82034 system off my 06 GT, mine is also adjustable, used 1 year, $400 with bottle, $300 without bottle. Shipping extra, if you come for it I'll give you a free bottle filled with N20!
Sorry it took a little while to reply. I will send you a pm with my phone number so you can contact me if you would like more info or pictures. I have a nitrous outlet plate kit. 00-10145 is the part number. I also have the bill it heated bottle bracket and a center consol switch panel with switches.
