Gryzynx, the 9" has an extra bearing to support it because it NEEDS it! LOL
Your spline count info is incorrect. I know, I own an original 69 dart swinger 340 4speed car w/8.75" rear end. It came with 30 spline axles from the factory...YOU GOT THAT RIGHT!!
The gear selection argument is laughable. Exactly WHAT gear do ya NEED that's not available?..VERY GOOD POINT..
Even a 741 case is stronger than a 9"!!!..LOL....
Get the FACTS!!!
