Hey, how did you get a picture of my clutch fork?
Seriously, my '05 Legacy GT just experienced this same problem on Monday.
Actually the pivot bolt has broken off from the tranny housing also. I've had the car back on the road for about 10K miles & this happens. I had the OEM clutch with a Spec 2 clutch & flywheel during the rebuild. I've been searching for possible mods, or a better clutch fork to avoid this same problem. Unfortunately my searches aren't going too well.
Has anyone found a solution to this problem?
