I have an old Racers Edge Billet Banshee head with domes. One of the domes is damaged. These domes were cut for a 7 mil cub so they are 68mm. You will have to get them recut. The plunge cut isn't too deep so there is still room to cut these.
As far as I know, you can't get replacement domes for these. I called John at Racers Edge and he lost contact with the guy that has the program to make these dome shells. These are different from Cool Head domes. This is a great design and used uses less orings than the cool head.
This is a great deal if you can recut these domes to fit your setup.
