Where can I find GSR transmission synros, and how much do they normally run?

 

try ebay....synchros themselves are inexpensive...the labor to put them in is where you will take a hit to the wallet

 

when i just put my synchros last month it was $240 at the honda dealership no one else had them and that was for 1st and 2nd synchro only and with an employee discount normally it would have been $365 I tried looking everywhere but no one had them not even ebay
