I had Dave @ RalliSpec rebuild my tranny back in Sep of last year, been great so far. Had to replace the reverse idler, gear and hub. Figured while he had it apart, might as well do the carbon baulk rings and new synchros. He only replaced what needed to be replaced and only charged me for what he replaced, which was two of the shift forks due to the plastic tabs being close to gone, a full synchro set, the reverse gear parts, 3-4 gears and hub and the 4-6 baulk rings. Shifts like butter now.
Can you recall what the prices were for parts, and also for labor? I'm expecting to do something like this soon.
