OK, I goofed. In my great mock-up of the Saginaw-Magnum interface, I ASSumed that the bolt hole I was using was used to bolt the WP to the TC cover (circled). Not. It's one that attaches the ALT/AC bracket to the TC cover. DOH! What this does is slightly dump on the cool tech I've spouted off so far. Not BAD, but a correction needs to be made, and I'm not sure yet how far it will go. First thing is that the end of the ALT/AC bracket is slightly thicker (by a fat 1/8") than the boss on the WP I thought I was using. That's enough for me to rethink just "milling" a little bit off to make up the difference.
