Your 9" issues likely were due to using too many factory ford parts. Everything but the housing needs to be bought aftermarket...and the housing needs a backbrace. Once you buy a GOOD centersection, you shouldn't have any problems. 9" are strong when built right, they just aint cheap.
Couldn't agree more, but I learned the "Ford" needs to be taken out of the "Ford 9"" after I sold the car. I have a brandX car with a big buck aftermarket 9', no problems at all.
