can't really help, but can advise that there is some variation out there. I made custom brackets (used the stock commonly available U bracket that bolts to case). I made a copy for a buddy installing the same denso alt on a wide deck and they wouldn't fit.
Also, that U bracket has 7/16 holes and the denso alt has 3/8. I used bronze spacers/inserts to tighten it up.
