which power steering pump to use? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When changing from a long water pump, back to a short one, with a small block chevy, does the power steering pump change also? Where does it mount, if it is different? Thanks

the pulley is different,and possibly shaft,be simplier to just use original style-

Also, GM switched from a woodruff key and nut pulley retention 74 and earlier to a 75 and later press fit pulley. At the same time, pulley alignment changed. (I have a 75 Corvette crank add-on pulley and PS pump pulley on my AGR pump. Summit sent wrong pump) All of the pulley alignments were different, so I could not use both of the 'vette crank pulleys, just the front one. You'd have to change water pump pulley and possible AC brackets. PITA.

I used a ps pump off a 73 p/u.Just mounted it on my 72 brackets. Works great so far
