This is how I have started making a accessory drive plate for my 1979 Ford F350 Crewcab 4x4. I received a scrap "D9TE-AB" 1979 Ford 460 engine block from a guy on the 460forddotcom website. I am making a true reverse rotation water pump setup using a single drive belt. I also will be adding an additional York Style A/C compressor to use for on-board-air. I plan to update the video as I progress, so check back often.
