rear 2 speed ratio please

The 48 f-6 didn't come home with me. I am looking at I believe a 57 now. I would like to know what the two speed ratio is if possible.

The numbers are as follow from the plate as best as I can tell.
Serial -f70z6h79788
Production code: 07M5527812
rear axle: 650-904
Trans: 5d1r
Thanks
Dave

My 58 F600 has a 6.33/8.81. There was also a 5.83/8.11 available.

The truck is a 1956 F700, and you answered your own question when you listed "rear axle: 650-904"

1948/56: Ford stamped the actual ratio(s) on the Rating Plate. 1957 and later use AXLE codes.

Eaton Model 13600 Two Speed Rear Axle / 6.50/9.04-1

/ 15,000 lb. Rear Axle Capacity.

Trans 5DIR = Clark 5 Speed Direct.

VIN (Vehicle Identification Number): F70 = F700 / Z = 272 2V H/D / 6 = 1956 / H = Detroit Truck Assembly Plant / 79788 = Numerical Sequence of Assembly = this F700's specific serial number.
