14" Rims and Larger Tires

.............does not list a 2.93 which I believe is my stock Barracudas gear ratio.

I agree, find out what you have first, easy to do:

Jack up ONE wheel with FRONT tires blocked. Put car in NEUTRAL, and release emergency brake. See if you can turn one wheel. If you can, you have no limited slip (suregrip). Now mark or just look at an identifiable point on the driveshaft, and mark the wheel. Just pointing the filler valve somewhere is good enough. Rotate the wheel TWO turns while counting the driveshaft. With the chart, it's easy to figure what you have. 2.7, the shaft turns 2 3/4 turns. 2.93, JUST barely shy of 3

If you are having trouble getting accuracy, get a friend to count the shaft, and turn the wheel 20 turns. A 2.93 would then be 29 and 3/10 turns

If you have limited slip (can't turn the one wheel) jack up BOTH rear wheels, turn the wheel only ONE turn and count shaft revs.
