Dracula vs Frankenstein
(1971)

Count Dracula (Zandor Vorkov) forces evil Dr. Duryea (J. Carroll Naish), secretly the last member of the Frankenstein family, to resurrect the Monster (John Bloom) in a vague plot to bring terror upon the world.  Aging hippies interfere but are dispatched.  

In the climax, Dracula and the Monster fight it out over the girl. Dracula rips the Monster limb from limb but is caught in the rays of the sun and turns to mulch.

Thanks Eph!
