Car is a 1967 250S sedan

What Years and models well Work ?

I want to Convert my Standard Steering to power Steering . I have the 1967

power steering Unit from a parts car ( 1967 250SE ) but not the Pump .
I note the 250S Front Crank Pulley takes Wide belts so https://trackeasy.fun/usps/ https://showbox.tools/ http://essaywriter.fun/ I need a wide Belt Pump unless I change out the Crank Pulley.



As the car sits now it only has 1 Belt for the alternator and fan and 2 empty wide slots for wide Belts it look like .
Of course I know 1967 well work but what other Years and Models well work ? Example a 300 Mercedes pump perhaps ?


the Car is a bit Hard to turn for low speed parking and I want the wife to learn to drive it as well . It is a standard column shift 4 speed
and to Learn to shift and drive it well be perhaps better with Power steering I think.



My Guess is that I need a early type Pump ?
