The ceramic insulator is 5/8 in. 16mm tall, threaded each end. ?Diameter could vary. Surplus sales does not list one that length. Just 3/4 in. ?The break seems to be old and parts of the ceramic have been lost, so there is little chance I could repair with epoxy. ?Likely hard to remove the screws without further damage. ?Possibly could make new ones with fiberglass dowel. ?3D print??
any other ideas?
