We just bought the car and it has an aftermarket chrome cover on it. What is the most common ratio?

You can spin the tire over and count the rotations of the driveshaft to know for sure.

The book I have lists the 3.08 for 4-speed cars and the 3.27 for the 5-speed cars in 1983.

To be 100% sure you will have to pull off the rear differential cover and count the teeth on the ring and pinion gears sometime. You never know what the owners before you might have done.

Look at your door tag for the code under ax, that will give the stock ratio.

The gt registry has it as 3.08 for 5.0 gt auto and manual and 3.45 for the 2.3 turbo gt.

That's the problem with most information.
Accuracy, who haz it?

I guess you get several choices and you can just choose the one you like best.

Mine is from a Tech Reference and Performance handbook by Al Kirschenbaum, written in 2000.

It would definitely be nice if ford had the information on a site to make information gathering easier.

+1,000,000,000

Yes indeed, my friend.

I have requested that from them numerous times over the years, but I guess it's too much trouble for them and you know they have all the info we could ever ask for just languishing on their computers somewhere.
