Do I need to get the ARP pump driveshaft, part # ARP-134-7901 AND the moroso intermiadiate shaft part number 22070 for the moroso 22145 oil pump and pickup assembly (for stock GM pan)??

Which is the correct rings to get out of the following?
-SLP-E-251X
-SLP-E-377X

EDIT: actually now that I look into it, neither of those are file to fit... No file to fit rings show up on summit when I search for sealed power iron rings for a 4.0" bore... What is the part # for sealed power or hastings file to fit rings??
