Whats the correct 1968 426 hemi p/s pump and pulley?

I have 3 different p/s pumps and pullies. The 426 hemi 1968 and later are different from 1969 - newer. What type is the correct, saginaw, fed mog or trw? also is the pulley the smaller solid or larger pulley with 3 openings. Any help or pics is greatly appreciated. Thanks Tim pm me here or email at timtlyons@sbcglobal.net

Hemi's had the federal pump all the way to 70 , 71 ??? . 68 older used the waterpump pulley that is the same as the B/RB so I would assume that the pump pulley is the same as B/RB 68 /older ?
