I keep running into those pesky double d screws in working on my AD. Screws on the seat and gas tank sending unit are small, tranny cover screws are large. I can't seem to find these drivers anywhere. Anybody know where I can order them? I have found some cluch bits that will work with some, but not with others. Any help would be greatly appreciated.
