alternator brackets?

It would help if we know what year your car/ engine are. If you have the large frame 105-larger amp alternator like this:

then you surely have the later water pump/ pulleys. I would think that a later pu/ van bracket would work, as long as you get "all" of it, IE the bracket, tensioner, spacers, etc.

I'm using "van stuff" on my 67, but then I did get it all out of a van, including pulleys.

Earlier round back, or later square back use the same mounting.

yeah i guess i should've been more specific. My car is a bit of mis-mash of parts. And yes, that giant brick of an alternator is what i have in my car.

Original engine(from when i bought it) was a late 70s 360. That engine died on me and a magnum 360 went in its place with a new parts store water pump for a 73 duster. And yes, using front cover off of that late 70s 360 so i could use the v-belts to get the car going on the cheap.
