94 Integra with 5 spd, Y80 trans. Gear grinding into third at 4,500 RPM or higher shifts (unless I double clutch). I would like to replace synchros but have only found two places to buy them. 1) Acura dealer wants to sell entire assy for around $285, 2) A place in Las Vegas will sell a "ring kit" that comes with all the brass rings for around $150. Anybody know of other sources ?
