Correct finish for non A/C blower motor.

[Stranglehold]

Sending out a few motors for rebuild/finish. Two blower motor (both non A/C) and a two speed wiper motor. Pretty sure on semi-gloss black for the wiper motor, but I've seen the same color for blower motors but also zinc plated. Wondering which is correct. Going in a "69 Dart Swinger 340. One blower motor is a spare ('74) the other I'd like to use as it's got the correct date code.

Correct on the wiper motor but gloss black on the blower motor.
