Alternator Bracket Help Needed

The bracket in the first pic is pre 67. Has a hole that oil stick passes through. It was overkill really. Later model alternators that had 2 belts that also carried the a/c had a similar ( heavy duty ) bracket underneath the alternator.
If I had to choose and/or gathering parts I would want the later model brackets, fuel pump and fuel supply line routing too. That line has the fuel filter placed vertically down in front of the water pump.
