There is a guy in the WCCC that has three windshield wipers also (427 body style). I believe his car came out of Mexico.
Can't recall what type of car it was? Let me think a little.
I could only find one pic of the rear of his car (hope it helps a little) The blue with white stripes at the pump.

Corbet comes to mind for the manufacturer.
This car is also corvette suspension and chevy engine from what I remember.
