1964-1966 Mustang Single-Speed Windshield Washer Pump, Exact Reproduction | eBay

This washer pump is for a Mustang, but looks to me as the same as the Mopar one or at least close. I don't have one of each in my hand to compare. The only thing I see is that the Mustang one is around $35, while the Mopar ones are sold for $70-80.

Any thoughts ?
