I have an untouched stock TB off my 87 GN. I just upgraded to a 62mm. It is bare, does not include any sensors or brackets. Worked fine when I drove the car last.
I can snap a pic if you want.
No idea what it's worth. Lemme know if you are interested.
I live in East Pointe (Near East side of Detroit). Could even meet you if you are close to me.
Thanks,
Mike
