Can anyone ID this rear diff for me? I want to change the gears and I need to know the correct series. It's currently in my '55 series 2, chevy 3100. I don't know if it's original or not. The 8.2 pictures I've seen appear to be more oval. This one is round. I can't find any reference to a round cover. Could it be from a car?
Thanks
Jim
