Bmw actually spec'ed a welded diff in a factory car in the 80's:
E21 group 5 had a spool in the hallibrand quick change unit that was spec'ed with standard cv axels for the e21 320 group 5 cars; bmw custom fitted a hallibrand 10" differential into the e21 chassis for pure factory racing purpose. Very very hard core modification!!!
It was a spool unit (meaning solid, what a welded is trying to be).
If you know what that is; it's not for street use!!! Nor is a quick change diff!!
