The 3.31 is an early tapered axle ratio. They also had 3.15 gears. Those gears can be swapped into later rears if you use green bearings, or swap out the thrust block with a later version. The thrust block is 1/4" shorter on the early open gear sets. Early sure grip units, starting in 1958, used the same thrust block size as the later differentials.2.94........ but what's one digit lol and haven't seen a factory 3.31 gear in all the years I've been messing with them. And isn't a 4.89 a Ferd gear?

I have never seen one of those. Are those built before the mid 60s? Most of what I've pulled are late 60s to the end in 1974. '741, 742, 489.
Original gears in the 741 housing in my 65 Coronet 440. 318 w/auto. The same axle I could not stop from leaking out the vent. I finally put on a bellows type sealed expansion device and that stopped the leak. I think Jeeps may use them and I know my quad diffs use them.

2.91s huh?
Pretty cool to learn new things. I figured that it had to be from something older than what I was used to seeing. Thank you.

Not a b body but the cbodys got a fact-tree 3.31 SG if you ordered a 440 Magnum and the big 4 speed.2.94........ but what's one digit lol and haven't seen a factory 3.31 gear in all the years I've been messing with them. And isn't a 4.89 a Ferd gear?
