Erich...you are NEVER gonna get one....I aint ever gonna get a blade...or the dang switches i need either. I actually was given the last "lone yoke" a couple of months ago...you get your struts made yet? I have a late model yoke i will give you...if it will fit...you want it? Its Ugly, but it might work? Ask Kim. Its a late model "plain" yoke...he probably remembers me talking about it.
What size is the stem on the yoke?, cakes had 2 sizes. As far as your blade goes, look for an early GE/ century or ? hub with inline rivets, I actually have one but it is earmarked for a project. I THINK it is GE from the shape of the blades.
