Vin decode.....help....

If you don't know how to decode VIN, you can try this decode. Always useful and quite cheap.

Unless your GT has been modified it has 3.27's.

Want to know for sure? Set the cruse control at 60 MPH on the freeway. Measure the time travel between mile post markers. What is the RPM's?

There's also a metal tag on the cover. The last digits has the rear end ratio.

Then there's the jack the rear axle up on jack stands. Mark the edge of a wheel. Turn the drive shaft and count how many turns of the drive shaft are needed to make the rear wheel turn one time around. If it's about 3 and a quarter.....

The VIN isn't going to contain the rear end ratio.
