Added a Saginaw PS pump for my manual to power steering conversion and the groove sits 1/4" further forward than the front groove of the crank pulley.
Crank, WP and Alt pulley grooves all line up. Crank Pulley #3614378 WP Pulley #2951836
70 340 aluminum WP passenger side outlet. It's a press fit 70 style oval neck reservoir.
I have a PS pulley that is about 6" and one that is about 7"
When mounted they both have the groove 1/4" too far forward to be lined up perfectly.
The Bouchillon Performance web site says "Pulleys that Are far apart, 1/8”-1/4” is Acceptable."
That just doesn't seem right to me...
