One of the quickest and easiest ways to check the rear gear ratio in a Ford banjo rear is to count the teeth on the ring gear through the filler plug hole. This was posted recently by Lawrie:

"One easier way to determine the ratio with out pulling the gear or turning wheels etc, is to count the teeth on the ring gear, put a paint pen mark on the ring gear through the drain or level plug,
this will tell you the ratio,
34=3.78
37= 4.11
39= 3.54 or 4.33
40=3.63 or 4.44
41=4.55
from the green bible parts book.

Hint: to do this you must have the rear wheels off the ground and transmission in neutral. I usually use jack stands under the small ends of each axle housing and turn the ring gear through the rear filler hole using a small screw driver.
