Magnum swap accessories question

An apology if this has been addressed elsewhere.

I am swapping a ’99 5.2L (from a Ram 1500) into a ’73 duster and will be keeping the serpentine accessory belt system. I have the brackets for alternator and power steering pump (I will use the A/C bypass) which I got through a local salvage yard (also from a truck).

I’m still rather new to this so my question is this. As my Duster already has P/S will I be able to use my existing P/S pump from the Duster with a serpentine style pulley, or will I have to buy an appropriate pump for this engine? And if I do have to switch to a new pump are there P/S hoses out there which will work?

Second – what is involved with switching to a new alternator suitable for this setup?

Any insight would be appreciated, thanks.
