Black Fans are later 70's issue.

Whats the date on your Pump?
Look for a small machined area underneath with stamped numbers & letters.

Whittek here in Chicago made the tower hose clamps originally.Do you see their name stamped into them?
Repops are date coding them too.

Show me the other side of your Check Valve.

Smog pulley has correct Number & Suffix,and looks real,but need to see it's otherside outside lip.

Not quite sure,but that could be a ASL Smog system.
