woot! finally found a local seller that can sell me a slightly used stock knob.
i was chatting away with one of my car buddies at one of the meetings today, and he mentioned his friend recently got a 370Z and swapped knobs.
so asked my buddy to ask his friend to see if he was able to remove it without damaging it and a few min ago i got an email saying no damage and willing to sell.
so, will have one for my G in the coming weeks.
my original plan was to remove my stock Z knob and use it on my G. but failed miserably due to super loctite mess.
