Yes , Booster Dewey is in Portland, Oregon. He has a website and he does very nice work. The standard rebuilt boosters are painted black. He does plating as well. Another source for a 64 booster would be Jody Anderson. He is located in Minnesota. He is the go to guy for 64 Chevys. He might have one already rebuilt, ready to go. Rock Auto is also a source but their boosters can have quality issues. 64 Chevys had two different boosters. Delco-Moraine and Bendix. Good luck.
