I have a 2007 350z roadster and would like to replace the front right counter weight..is there an aftermarket to replace the oem.

 

I think people just toss it

 

Apparently the counter weight is attached to the chasis drivers front. A runner bushing absorbs bibrations from the chasis at certain speeds..i found a part 350 with a good rubber bushing. I located one on ebay but the bushing was cracked.
it is easy to install..
