I am going to the junk yard to get one off of an atuo SC. So I can get rid of the tall stock 5-sp diff that I have. The problem is that they have pulled it off the car and set it next to all the other diffs almost 100. The say the know which one came from the SC automatic But I want to confirm w/numbers or anyway possible Thanks for input Nick

look for the metal tag thats attached to all the pumpkins. Should read like this: 3L27 8.8 this would be a 3.27 ratio with trac-loc 8.8 rear end. You don't have to get one for just an SC, as the some V8 birds did come with 3L27 8.8 rears, though most will have just an open with 3.08 gears.
