Pulley ID help

Thanks everyone for the help, 73abodee, #2 is 2 pulleys together, but it sure looks factory. So with ac, the ac belt runs round the crank pulley, the wp pulley, ac comp pulley and the alternator?? It runs round 4 pulleys?? That belt would be as big as the one I would get across my arse in public school!!

Now my questions are, which sb and which bb?? I dont need extras and I want to keep what I need for my 69 340 non ac non ps cuda. As well as keeping any sb ac ones related to dads 67 273 ac/ps cuda.

Another cry for more help I guess. LOL



Thanks again guys
