Just saw this!
BTW.. that is a VERY expensive custom DOB 200amp alt. That DOB bracket is specific to that alt also. If you part it out (I would) you may want to check into a new alt bracket for the factory alt if someone wants it. IIRC, that bracket "should" still work with the factory alt as well, I can't remember if I even tried or not. The little support brace is also specific to that alt as we did not have time to fiddle with a rear support brace for it but it works. The guy that has a built motor running lots of boost/rpm definitely needs a rear support (and probably an 8 rib setup)
