Dont worry how old you are... it is the mileage on your body that adds up.

Need the numbers stamped into the forward side of the axle tube. The numbers you have posted are just casting #'s for the centersection and won't identify the rear end.

12-bolt car or 12-bolt truck rear?? Can you post a picture of it?? How wide is is from wheel mounting surface to wheel mounting surface??

It appears the same casting numbers were used on both 10- and 12-bolt truck rear ends. The reference I saw on the 12-bolt was that it was in a '84 Suburban.
