Engine Heater Tubes

[Superarnie Mk2]

Dear all,
   
   I'm trying to source a set of the engine heater tubes for my Superblower, that were fitted to the 5.0 EFI engines. I think they were a bespoke component made by AC Cars because the stock Mustang item doesn't appear to be compatible with these cars.
   
   Has anyone with an EFI engined car, removed or disconnected their cockpit heater, and therefore have a spare set they would be willing to sell me.
   
   The efi engines have the engine coolant sensor fitted into the assembly.
   
   If you  have a non EFI car I may still be interested in any spare heater tubes and I would have to relocate the sensor.
   
   Many thanks
