Up for sale is a pair of Elephant Ears mounting brackets for a Mopar B or RB engine.  I got these from a retired drag racer when purchaing some Hemi parts.  These would work on a 383, 400, 426W 440 or 426 Hemi.  These are fabricated from 1/4" steel so they are heavy duty.  I have shown them mocked up behing a old wate pump housing for reference.
