The bat wing is a stock Dana 44 rear end cover that I modified. I had a local machine shop water jet, out of aluminum, the tube shapes needed to insert into the holes of the wings. I then covered the front and back with aluminum skins. Then ground the welds and polished. I would love to post some pics but they are all too large and I don't know how to reduce them. I know that Paul Newman,
www.newmancarcreations.com has a batwing that he has produced but I don't know anything about it.
Thanks for the kind words srh3trinity.
