Another pulley question

You need to use a complete set of pulleys and brackets from a '69 and earlier model. Mixing '70 and newer parts with the '69 and older parts just doesn't work correctly. If you don't have A/C, you need to get a non-A/C setup also. None of the A/C brackets and pulleys are the same as the non-A/C version except for maybe the P/S brackets on some models/years.
