Wire mesh for SC Exhaust sidetrim ?

I was able to buy the right mesh from Stan, all redy cut to size.
Other sources proofed complicated , either they would not sell to Swiss residents or they ask you how manny ton's of mesh you want.
Just one seemed to be happy to sell 20 squarefoot of mesh but shipping was much to high and what should i do with 20 squarefoot of mesh ???
So now i can refurbish my sidescreens with the correct brassmesh and get it replated nicley.

Who can name me a supplyer for the correct brass wire mesh used in the sidetrim of the SC exhaust trimopenings ?

material : plane brass,
structur : woven wire net, square aparture,
wire diameter : round 0,0393 zoll,
mesh size : between two wires 0,1574 zoll,
size needed : 40 zoll by 40 zoll

i should be able to contact the supplyer by e-mail or internet, plaese.
Manny thanks for your help in advanced
