Ok guys well a friend of mine is building me an axle he got for me supposedly it is a 9 inch we were told and it does look like it. But after i ordered the gears (4.11) something has make me guess we actually don't have a true 9 inch but a 9.5 or a 9 3/8 as some of you know.
I will post some pictures for you to help me clarify what it is that i have.
The end product
how ever what make me wonder that i don't have a 9 inch is because i ordered gears and if measured from the bottom (no teeth) is 8 3/8
however the gear we pulled out of the axle measured 9 inches at the bottom so it is a big difference
i checked here but i need more information than what is provided
