Re: QuickPerformance Ford 9in
I didn't do any of those options, I actually chose option 3 and bought myself a Midwest Chassis Fab 9" housing and axle package with their 3rd gen specific mid length torque arm and crossmember. I quickly mocked it up in the car before heading to work last month and there's tons of clearance. I should've just went with Midwest Chassis the first time. Kinda sucks I had to do it twice but that's life I guess

Re: QuickPerformance Ford 9in
I got a QP 9" in my car.
Bolted in, with minor mods of course.
I did it about 11 years ago.
Ordered it with disc brakes and the torque arm mount and the fill bung.
So far so good!
Have 35 spline axles and been a best of 1.284 60ft.

Re: QuickPerformance Ford 9in
Auto weld chassis.com is who I went with. They integrate the torque arm to the rear to give lots of adjustment and it hooks to the very top and bottom of the housing giving lots of clearance and a more straight line approach.
