Steering Pump ID Help......

According to all the sources out there at parts suppliers, there were 2 different power steering pumps installed in a 1967 Barracuda with a 273......

A Chrysler, and a Saginaw.

NO ONE can tell us the difference or how to ID the pumps for a seal kit.....NO ONE so far......and there are no pumps available for this car between here and outer Madagascar.........

Can any of you'se guys tell us how to positively ID the pump that's in the car?
