Rear End Gear Type
I cannot locate the code inside of the glove box but my rear diff is stamped with 2.73. Does this mean that I have 2.73 gears or is it just the size of the rear end.

If you want to check your engine speed in 4th gear, here are the correct rpm values. 
3.15s
2000 rpm @ 72 mph
2100 rpm @ 76 mph
3.73
2300 rpm @ 70 mph
2500 rpm @ 76 mph
3.90
2400 rpm @ 70 mph
2600 rpm @ 76 mph
I didn't calculate for the 2.73s, but if you're turning less than the 3.15 values then, obviously, you have a taller gear.
