Looking for a Water Rail

Looking for a Water Rail
I need to get a water rail for my S Type. The outlet end for the heater snapped off and I don't want to try and have it welded back on since the threads are damaged meaning it will need to be heli coiled which will probably leak. It's part number C15800/2.
So checking to see if anyone here has one they'd like to unload.

That got broken off trying to remove a corroded heater piping steel nipple. It's better just to cut the nipple & collapse it. Then screw in a new one & maintain coolant concentration thereafter.
Wish I could help but I'm keeping my spare. They usually corrode at the pipe at the Otter switch end and I have a pristine one.

Those water rails are common to MK1, MK2 and S type 3.4 and 3.8 engines.
However, they have become extremely scarce to near impossible to find (as Glyn says) because they corrode the pipe at the end near the otter switch.
I have been trying to find one for a friend for a couple of months now. I do have a spare but I am keeping it for my cars.
I suggest you get it welded and helicoiled and use a jointing compound like "Stag" to stop any leaks.
An alternative would be to weld up the heater outlet and redrill and tap the hole for a new fitting.

That is good news for you.
Pay extreme attention to the state of corrosion on this pipe. Choose a good one. I also replaced all my heater pipes with stainless steel. They also have a habit of being badly corroded from people being careless with coolant concentration or just using plain water. When these cars had little value they were carelessly treated by many.
