I'd assume that it's just worn out - my terrible side mirrors would droop when the car was running. I haven't looked at it, but I assume the inside mirror uses a similar tension-fit to hold position.

Nope, same exact part. Never had an issue in my old 240Z either.

Come to think of it, I still have my old 240Z mirror. Wanna buy it?

Not sure, maybe.

It's not drooping, and the joint behind the mirror isn't loose. It shakes where it snaps into the roof.

Wow that looks great. Where are you located? I would be willing to pay you to re silver my mirror. If you are interested PM me a price and your address and I will ship you the mirror, cash and a return shipping label. Thanks
