My 1996 camaro z-28 need the rear end replaced, so were is the id tag, that gives me the correct rearend , in hte car and should I pull out the complete rear end and have it rebuiled, and then reinstalled it myself, as I have R/R reare ends before saving a little money, then I can replace the rear shocks and as it only has 70,000 miles check the unversial joints fro wear and any damage, so again is the ID tag on the Pass side right side axle tube facing the pass side thanks

The tag should be on one of the rear cover bolts, if it has been removed all you need to do is remove the rear cover and count all the teeth on the ring gear and the pinion gear then divided the number of ring rear teeth by the number of pinion gear teeth and that will give you the gear ratio of the rear end........GOOD LUCK

If you take the VIN # to a GM dealer they should be able to tell you the original rear end that the vehicle came with. If you are going to take the rear end to a shop they will be able to tell when they take it apart. If it is a posi rear end it will have a tag under one af the cover bolts (if it has not been removed) Once inside a posi rear end is immediately identifiable from the clutch pack. Also the number of teeth is stamped on each (pinion and ring) gear. Divide ring gear # by Pinion gear # to get rear end ratio. Didn't get directly to your question, but I hope this helps. Let me know. Thanks
