...when I can compare both pumps, side by side, I will post what I discover. What we already know is, the Windsor 'shorty' pump:
The Intake is on the correct side, Drivers' side, Left Side of Engine.
Correct Rotation, Clockwise when mounted against the Cleveland Timing Cover.
The Majority of Bolt Hole Alignment is Correct. Those that are Not, can be Machined.
The Pulley Mounting Flange is Universal and Correct. Excepting for the Pilot Diameter of 0.75".
I know I can Lower the Alternator 4-5 Inches and it Only must be Re-Positioned Back 1.0", to Align with the Inner sheeve of the Crank Pulley. It will clear the Lower Angle of the Firewall at 8 Degrees.
Stay Tuned
