Whatever fair value is mate. I sold the car so no longer need them! I have a cat if by chance you need one of those.

I had a dreaded leak so bought both parts from Ford. I'm sure they were circa £80-90 but was ages ago so not 100%.

It was only the seal round the thermostat I think that was fucked so if I remember right I changed the smaller piece just for the sake of it but not the other, again I'd have to see the pieces to remember why. I think I was going to return the bigger more expensive piece.

I ended up keeping the piece and obviously still have the original smaller piece that was fine.
