Air conditioning belt tensioning pulley with new bearing. This adjustable bracket and pulley was used on all 1970-73 351 engines that came with A/C, as well as 1970 428CJ & 1971 429CJ. This part often has a casting number of D0AA-8A617-C1 but not always. This adjustable idler pulley is identified by having the large bearing pulley.

large bearing, but carries a casting number that starts out D5..., or
