Just bought a 1976 127 and had to take the head off (spark plug blew out on first drive).
Whilst putting back together I think a piece has gone missing: there is a ball attached to the heat shield (that sits over the exhaust manifold as it exits the head). It looks as though there should be a piece that has a socket (to fit the ball) and forms a support to one end of the cross rod. Could be two pieces I guess though. I don't know what the piece looks like as I didn't pay too much attention when I was taking it apart.
Hope that makes sense - anyone know where to get a replacement?
