Nice table and the link works for me. Do you need a dust cover or another base? I might know a shop which has some NOS ELAC/MIRACORD stuff.
BTW, with changers, typically VTA is a compromise usually for the middle record of a typical stack of 3-5. Obviously, each record is going to have a different VTA but when these werre designed, conical and ellipitical stylii were all that were available and VTA, as an adjustment, was not thought of that much, or less critiical in the overall scheme of things with changers.
Now, if there was ever a changer that automatically changed the VTA with each record, there's a device!
