Hmmm. I had a pair of Leda struts but have gone over to Gaz now. I also converted from the Beta top mounts to the spherical joint ones but I can't recall for certain if the Beta type top mounts transferred over to the spherical top mounts. What makes think they were transferred is that I have just found the old bottom spring pans. I'll have another look at the weekend but I would have expected to find top & bottom mounts together if I had them.

But, if I do have them they'll have quite a wide hole through the centre as the top spring pans for Beta top mounts which are located by a hard plastic protrusion from the base of the Beta top mount. I suspect that's what you've got at the moment Paul? Is it possible to get a spacer machined from a hard polythene block to fill the hole?
