Don't forget if you get a Mark Williams, the axles will not fit. I have MW's for mine,
but I had to get new axles when we took the strange unit out.
For that power level, moser or strange are plenty. As someone said,
old metal gets weaker over the years. Good luck.

I broke 3 stock ford cases before I bought a strange piece. The pinion support is the problem, it lets the front of the pinion flex up and this puts it in a major bind. Mine was breaking the case in the back where the small pinion bearing is. If you don't catch it in time you will KABOOM the whole case like you did. I broke 2 in back to back weekends in my cam only 6 speed car. The stock case isn't the issue, it will live if you buy a good pinion support.

Thanks for the advice on the pinion support guys! I never thought about that being the weak part... I knew that they made aftermarket ones because stock ones were weak, it makes sense. I'm gonna go ahead and replace the third member and the pinion support with good stuff this time just so I don't have to worry about it again anytime soon. Kinda scary to have the driveshaft still spinning after a break like this, I definitely don't wanna be replacing my 6 speed...
