Power Brake Booster Restoration

I'm looing for a good company to restore my 72 B-body booster. After looking at a lot of posts here, I reached out to Power Brake Booster Exchange (booster Dewey). So far, no replies to email or phone calls and voice mail is full. Are they still in business? Can anybody recommend a place closer to Michigan?

I just had a booster done by Booster Dewey (now Booster Steve) Told me that the phone and internet had been acting up. I spoke with Mark

That's good to know... I was very hesitant about sending my booster to them no contact.
