Father-Son 1974 Duster Project

Mopar basic 101
69 and early are different from 70 and up, will not work or align.
The pic 67 cuda posted is a Federal pump, parts are expensive.
Mopar also used a Saginaw pump which parts are easy to get for, most Chevy's had them.
Buy a complete set of everything from the junk yard or somebody here, do not mix and match parts. Take the pulleys and everything off the same car to ensure fit on yours.
