Differential ID
How can I tell what Differential I have? The car has had a lot of work, the rear end has had new gears and I don't know if they just replaced the gears or the entire differential.
I know nothing about the Corvette rear end and no I don't have a book yet

You would rotate the tire/wheel one revolution and calculate the axle ratio by the number of rotations of the drive-shaft.
A single rotation of the wheel/tire and three rotations of the drive-shaft would be something near 3.00 etc.
This is actually quite accurate because there's generally a spread of a substantial number in the available ratios in a particular rear axle build. It's difficult to confuse yourself.

Don't think so!

A single rotation of the wheel/tire and three rotations of the drive-shaft would be something near 3.00 etc.

A quick way to tell if it is a D36 or D44 is look at the top of the pumpkin where it attaches to the batwing, the D36 has a center bolt (3 bolts) across the top where the D44 does not (2 bolts).
