Rear end gear


Been trying to find the stock gear ratio for a 63 parisienne non-posi rear end.  Any help is appreciated.

Between 3.08 to 3.36 are most common with PG trans depending on model & equipt.

Parts Catalog No 692 1958-69 seems to indicate the following for gear and pinion units
1958-64, 3.08 ratio - 12 pinion, 37 gear teeth, part #3758549
1958 -64, 3.36 ratio - 11 pinion, 37 gear teeth, part # 3798437
1958-64, 3.55 ratio - 9 pinion, 32 gear teeth, part # 3795479

Also found a detailed 1966 Differential Identification Code Table listing about 75 axle codes.
Not sure if this applies to years other than 1966 . The code can be found stamped 1/4" high on the bottom of the right hand axle tube approximately 3" from the carrier.
DA = 3.08
DI = 3.36
DQ = 3.55

The guy in Chatham I think is also the Moser rear end dealer. I see him at all the major swap meets.
