NOS Ford A/C idler pulley for adjusting a/c belt. Not sure which years it fits, but I think it will fit all V8 engines. The part number on the box isD80Z-8678-A YS 103. There is another part number on the bracket itself, which is D80H-19W653-A1A SPC. The box is rough, and the pulley will need to be painted to make it look nice. The bearing is solid and turns freely.
