i installed my tracker 5:12 and it was ok till the other day i hit a 3 ft shelf with both front tires at once my chromolly shafts held ok but i cracked the housing and chipped my ring and pinion . i have a toyota front axle but cannot find 5:12 gears for it and do not have a toyota rear so im trying to match up my gears . does anyone know if these are available? thanks for any help
