I still say they're 9's. Because you can pull a center out of an old ford and bolt it into the best housing out there. Sure you need axles,but you need them for anything.

Ratio changes aren't bad on a 60 if you keep the whole setup together. I have all my 60 gear sets where they're just pull out one and bolt in another. Ultimately cheaper than swapping entire 9 centers. Almost as fast as the 9 too, but not quite. A gear set, a spool, a setup kit with bearings, and done, no case to buy. Bout a grand cheaper per ratio
