Rear End Gear Ration
So I am trying to figure out the gear ration in my 71 LWB. I pulled the dif. cover adn was unable to spin the yoke to count all the teeth on the big gear and the small gear...however the following numbers are on the big gear: 3817778 11.41 GM 9-70 2........does this make sense to any one? I divided the 11 into th 41 and came up with 3.72.......is that my gear ration???????

Re: Rear End Gear Ration
If 11 and 41 are on the ring gear,it makes it a 3:73.
