Timing cover
@MassDart you probably are already aware, but just in case. You'll need to put timing marks on your balancer for the passenger side timing on the cover.
On my Magnum I kept my v-belt front end with a driver's side water pump and a 70 cover. I painted different color lines on the balancer at TDC, 20, and 36. It's not super easy to see the timing marks behind the water pump and power steering pump, but its doable.
