Don't know the answer Dave. There use to be Hobb's Speed Shop run by T/F racer Phil Hobbs back in the 70s & 80s, he curently lives in INDY. And there is a guy that works at Chrysler named Greg Hobbs that is a Tool and Die maker, he use to do some work on the side....I don't know if that is him or not. I will do some rsearch and see what I can come up with.
