Took the differetial cover off the front on my 77 K5 to replace an axle seal...had fluid leakin out of a tube. Found parts of a bearing in the bottom so I took out the ring gear. the rollers from one of the differetial bearings fell into the hogs head when I took it out. The problem Im having is finding the spacer that sits between the housing and the race. The race and the spacer on the side that the bearing let go on got ground down pretty bad and are unusable. I've found the race's and bearings but not the spacer. Any ideas on where I can get this would be very helpfull. Also if there is anything special about bolting the ring gear back in when I find the parts that I need to know that would be helpfull too....thanks in advance for any help....Dayne
