Thank you very much.
I will wait to see if I get a relpy from the rubber company that I emailed.
If I have no luck there I may send you a pm with my details.

I don't think they need to be rubber, I think they just stop water and dirt from being thrown off the front tyres into the engine bay.
If I can't get rubber to work I may just make a fibreglass one.
But I do like the idea of rubber.
It would look factory, which is what I am going for in my atempt to make these parts.

I am amazed at how many people on here are willing to help out.
A big Thank you to the datsun community.
