Original inner wing heat shield

[taylormj4]

Hi all,
Anyone know a source of the original inner wing heat shield material ?
It seems to have two components: the blanket and a foil covering. The foil covering was damaged when I had a garage in Cardiff do the exhaust manifold gaskets. Didn't worry about it too much as the blanket was still in place but the carpet on the other side of the tunnel is suffering due to the heat !

Thanks both.
Trying to keep the car as original as possible. The stuff in that link looks pretty close to original.
Anyone used it ?
