Close up pics. Some flat stock bent, some 3/8” DOM for spacers, a turnbuckle made from the same DOM and some old heims, and an idler pulley that was 3 or 4 pulleys from various different engines all rolled in to an alternator mount. Oh and I had to turn a spacer on the lathe to get the 7 rib pulley on the Delphi alternator.
