I'm a bit of a noob when it comes to drivetrain and transmission stuff so bear with me. I'm looking for a more cost effective alternative to using a T2T4, and was wondering if the I could use a differential from this trans or a TWT4 in an F22b 5speed?

 

Last time I messed with one it was a wider differential and required the original casing. So for the common Joe, its not feasible to swap that diff into another h/f trans.

 

No it won't fit. Just get an lsd from synchrotech and swap it into your existing tranny.
