does anyone know where i could just find the snap ring for 5th gear? i tried re-using the old one and it fell off driving down the road, then i put one on from another lower mileage transmission, worked great, then i had to take it off to do some repairs and tried using the snap ring again and then that one fell off goin down the road again....iv tried looking everywhere but i cant find a place that sells individual parts..any ideas?
