need help to identify the rear differential

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?

The only way to tell without counting
teeth is by marking the driveshaft and
marking the tire, then turn the tire one
revolution and count how many times the
driveshaft rotates. One rotation of the
tire and aprox 3 1/2 rotations of the driveshaft
will equal 3.55 gears and so on.
