swapped motor out with a 396 need help

As in the title I swapped my motor to a 69 big block or 68. But I tried the vbelts and it squells like hell when I give it gas to im swapping the vbelt and converting to a serpentine belt. I want my ac and power steering. I can't find the brackets and a pulley for it. Can anyone help me with part numbers? I'm not trying to spend 500 on a kit when I only need 2 things from it. Thanks. :banghead:
