This used OEM part is a vintage Ford 67-68 Mustang air conditioning fixed idler pulley and bracket assembly, typically used on classic late-1960s Ford vehicles equipped with a small-block V8 engine.
The numbers raised on the cast metal piece-which appears to read C8ZE followed by a design suffix-are a classic vintage Ford engineering/casting part number.

V8-289 cubic-inch
V8-302 cubic-inch
V-8 451 Windsor (351W) V8 (1969)
