Excalibur: Do we supply or fit external connectors not approved by our engineers, the answer is no, all our connectors are fully bonded and fitted into the pod end cap we do not feel the existing external connectors provide good value for money and do not perform to the level and quality we expect, and therefore do not conform to our high standards for provision of service and repair / modifications, therefor we only use high quality components in our modifications.
