going to pick the lock ring pliers up at granger, they have a local shop. what size bolt goes into the threaded opening on the birf??
I believe it's a 12mm bolt (head size). When I do a trail repair and need that bolt I usually just pinch one from somewhere under the hood. There are a lot of bolts already in use on a Land Cruiser that will thread in there. Better to find a longer one, like 1-1/2 or 2" +. this lets you hold the Birfield out, while you put the snap ring in, otherwise when you try to put the snap ring in, you push the axle in and loose the groove that the snap ring rides in.
