Re: 12 Bolt GM ?
Larry--I forgot to mention that that code is for a 68 or 69 rear end however see what the date code cast into the ribs on the left side of cast iron differential are ---also what is the serial number of your car you might have a very early 70 model and they had left over 69 housings to use up when they built your car
