I'm going to use the ford 9" 1 for width 2 for the large aftermarket support.
I'm pretty sure the 9" is going to be better in the long run, its uses in Drag cars, hotrods, baja trucks. so there is tons of support for this axles and when i break it i'm just gonna toss in the chromoly's if i break it again you tell me ( I told you so)other then that i am confident with this axle.

But the 89swb is for sale minus gears and Limited Slip <img src="/forums/images/graemlins/cheers.gif" alt="" />
