Gold Zinc just like original.
This part number says it is for a 350 engine.
However is is the identical match to the genuine 253 HQ bracket.
Another parts jockey stuff up I would say.
Note the domed head on the flat blade screw head.
Also different thread lengths.
Bracket is Gold Zinc.
Screw is silver Zinc.
The attaching bolt and the spring washer are also silver Zinc
