I found this. Would it be the same company?
Not necessarily helpful, just history.

"Mark “Mad Dog” Delcamp spent his first nine years in the header industry working for JR Headers from 1973 up until their purchase by Hedman Hedders in 1982. Mad Dog remained with Hedman for seven additional years before deciding to open Mad Dog Headers in 1989. A small business atmosphere and low overhead ensures each header built by Mad Dog has over 40 years of quality manufacturing experience behind it. "
