Upgrade to later model steering pump?

[siggyfreud]

Hey all,

So I have a mid-80s power steering box mounted that uses metric fittings. I to shift how my power steering pump is mounted a bit, and install a new pulley. I figure if I'm going through the trouble I'll swap in a new pump, since this one has been on there for a long time.

Would I be able to get a pump from the same generation that would use metric fittings as well so I could use new stock lines, or would I have issues mounting it to the Gen I SBC?

Thanks all!
