Tell me the ring and pinion counts

[Neil Mylar LakewoodCA]

Can anyone tell me the numbers of ring and pinion counts for the different gear rations?

I have an extra rear end with a 9/37 R&P. I assume it is a 4:11 rear end.

so, 9/37 = 4:11
what are the numbers for the other gear ratios?

10:37 3.7/1 Very early 1928
9:34 3.78/1 Commonly referred to as the standard ratio.
9:37 4.11/1 Most suitable for pick-ups and load carrying or vehicles with a high
overdrive fitted
11:.39 3.54/1 High speed excellent for the touring car.

Trust this helps.

I'm not sure what month the 3.7 to 1 ended, but my 9-23-28 tank date 28 Phaeton still has it.
