Hi guys today I was visiting one of my rodder friends in the big smoke (Auckland) and was tell him about this conversation on stainless split bones and he told me to get your to try "Fatman's Eng" . That is what he remembers as the name of a hotrod fabrication business up there that sold S/S bones and had two types,normal or with lightening holes done probably. Steve, my friend used to spend our winter up in LA building hot rods for a wealthy movie studio guy so got to know where to source stuff from. I hope this is some help guys.
