The Lynx head lights are the same as those found on a Cab11 or Cab12 Blitz and tighten up by a single nut from under the mount.
I was lucky that one of the mounts still had it's basic shape and was not too badly mis-shapen.
The other one????
I formed a bowl shaped piece with the same sized convex shape as the good (?) one and I welded into position.
cleaned it up and then cut the six sided hole in the top
a small amount of filler and there they were finished.
