I got mine in from Macs and tried to install it in my 8ba flatty yesterday.
The bracket goes on perfect but the alternator seems to far back and doesn't quite align with the water pumps correctly. I have the alternator installed behind the bracket.

Does anyone have pictures of their setup in relation to the pulleys?

 

Turns out I have a wrong application for my 47. I sent it back to Macs and am waiting on a new one to get in.
