Sadly there's a lot of "un - factory" about mine it has had various "improvements" and I would not necessarily believe it is the correct alternator although it is kicking out 70A and mine does have a Factory bracket.
Essentially the two lugs at front and rear of alternator are mounted upwards, and are either side of plug 4, that means the normal length lead wont fit, I have used another one that's longer and fed it over the top of alternator lug and into the middle, its pretty functional but not clever.
I have had a close look and this alternator it wont be reversible to put single lug at top as in this photograph - that would be my ideal fix- so I think I will go down avenue of newer smaller motorsport alternator and fabricate custom brackets - as no one else has responded I assume the original bracket as photo that I am after is like hens teeth.....
