need help to identify the rear differential

943 Views 3 Replies 3 Participants Last post by  Sleepertsi
I just bought an 03 gt convertible that 's had a ton of work done to it and when I went to change the rear diff fluid there isn't a tag to say what gears it has in it. The only tag on it says it requires 75 40w full synthetic fluid only. So how can I tell what gears it has or if it's a different rear diff?
