Hi Sean,
These tie rod ends, It might say Lockheed on the packet, but I think they were made by Thompson, another company in the AP Group. Sadly I do not have a catalogue of these. To confirm, I checked the Commer Q4 parts list and although these ends are not for this vehicle, they did use Thompson ball joints and numbers were prefixed with J.
No idea on the water pump, sorry.
cheers Richard
