Borgeson box help

So issue im having is, which hoses do i buy? My factory pump looks like a saginaw style pump and so im looking at the site PN 925113 seems to be the right one becuase i bought the box with the 1-1/8 shaft but the site says V8 application only and thats whats throwing me off. Just wanna be sure, any feedback and advice helps its going in a 1970 valiant with a 225/6. Also should i buy a new pump too? Mine doesnt leak but i dont know if it will work with the new box.
