1975 35 Double Alternator

Can anyone help crossing a Prestolite alternator -ALE 6221Y-1H. it is on the port side of a Chris Craft 350-Q25 engine?

The old Prestolite Alt used a external Regulator if OMC. Later used internal Reg Prestolite/Motorola type. Could chose another using the link chart and just rewire accordingly. Easiest way would be change to a "one wire" Alt (Delco self excite)
