There is a bit that goes onto the side & then tilts down towards the manifold. I have the wing-nut to hold it in place, but no side piece. The pictures I have in brochures feature this. Does anyone have on they would like to sell me? I like to have my car 100% factory correct if I can.

  Picture taken in 1960. Funnily enough it still looks like this!
