That's why I believe at least some of it has to do with the TruTrac. The only way for me to have anything done with that is to buy another and pay to swap it in. That's rather costly to just try. I still may. It's no fun pulling the 9" and even less putting it back in without damaging the Lube Locker gasket. I'd still like to try a WaveTrac.
I did look at the 8.8 but it would not be a direct swap due to the way the torque arm attaches to the case of the 9" in Speedtech's design. That would've definitely been something I would've rather went to as I'm a fan of it. I didn't ask Donny if he saw a way to do so without a lot of re-engineering. That and rubber bushings may help at least in theory.
Finding NOS Ford gears in a ratio other than a non-street friendly ratio is impossible. I have no interest in anything over 3.25 and would ideally like below 3.0 these days.

It never occurred to me that it wouldn’t work with the torque arm.
