While I was cleaning the engine mounts I had a look at the original earth braid strap that attached on to the mount.
It Was all black and green and looking very poorly but after a good bit of cleaning it came up very nicely I think.
If only it would stay like that
I couldn't resist mocking it up on the painted chassis for the laugh to see what it would look like and check the earthing capability was still good, which it was!
