64 Dodge broadcast sheet decode?

[fwi]

I have searched online, unable to find this. My broadcast sheet shows on the top line a #94 for Axle and #57 for Pinion. I know it's a 741 case 8 3/4, but what about the pinion?

Part number 2204 357 dark purple speedometer pinion. Goes in the transmission. Sized to fit gear ratio and tire height.

Are you looking for your gear ratio ? Early "B"cars are stamped on the rim of the 741 case.Should be on the passenger side close to the bottom. A Slant stick car usually came with 3.23. My 63 with a 318 stick has 3.23. That's where I found the stamp mark. Rim meaning the outside edge of the case that meets the housing.
