Don't Know My Rear from a ?????

["Dick Benjamin" <dickb@xxxxxxxxx>]

Jack up one side of the car only on a safe surface, with the front wheels
blocked.

Put a strong jackstand under that side, put the transmission in neutral, let
the parking brake off.

Mark the tire which is off the pavement where you can see the mark on it
from under the car while you rotate the driveshaft.  Make the tire do
exactly two complete turns, paying attention to how many turns you do with
the driveshaft.   The ratio is the number of turns you count.

it might be kind of nice to know what gears are in the carrier.     It's an
8 3/4", and it's an open differential, since one drum turns the opposite
direction of the other when I give either of them a spin.

I'm clueless on an open rear end.   And, there's no tag attached displaying
the ring and pinion ratio either.    Does anyone know what the trick is to
check an open rear end for ratio?
