So i found a car for sale i think on NASIOC and its got blown syncro's for 5th gear. the guy selling it says it "shifts fine with the clutch in". how much of a pain would it be to replace, is it really that big of a deal, and is there shrapnel floating around in the trans from the missing syncro? thanks for the help! (also has a 6 puck clutch...maybe the stress helped?)
