Ajustable strut tops are great, but you do a lot of work to build them, set them once and rarely change them again. The other problem is the possibility of them moving.
I found that it was better to make a top that simply gives as much camber and castor as possible and use ajustable radius rods (modified Falcon) for final castor, and a minor strut bend for camber changes.
I've posted some pictures and have my original CAD drawings if anyone is interested.
