I assume since it is a OO code 68-70 era? Pictures are what we need for condition of the external casting... Next factor is want... I would say 3.42 is a wanted item in that era 68-70 If the limited slip is good (need mileage on the rear) Gears in good used normal wear condition Clean painted external 500-1000 range. Jim JD
please disregard the information that I gave to you. I was 100% sure this was an OO axle. But it's not. The one I have is a 342 post but I can't find codes anywhere. Ring and pinion has 1382744 41 12 gmc. Can someone help out? I'm sorry for the mistake. Frank
ON = 3:64 There are some guys looking for that rear. The other question is what year is it exactly. The 68 and early 69 had a sealed axle bearing. The late-69 and 1970 had a roller axle bearing.
It wouldn’t be the 1st time I’ve seen a housing with the wrong code,or the guts don’t match the code.
