Which Alternator Brackets?

64 Valiant from slant six to B engine. Which factory alternator bracket set will work? Stock 906 iron heads, stock block. Alternator on the passenger's side now and that's where I want it to stay. It doesn't have to be 64 brackets, just so it mounts on the passenger's side. Alternator only is what I am running now and will run. Maybe A/C added the distant future. Thanks.
