Fan mounting options

I have now made up a metal cover plate for the breather tower and a rubber pad for the fan shroud to sit on. I also played with the strap a little more. The mounting on the right side (other side to the distributor) is fine, but the other side is not so good. The strap fixes on one side to the distributor clamp stud, but the other side needs some support. I might put in an aluminium block, held by the case through bolt, with another stud to fix the strap to. Any suggestions would be most welcome. Here are some more pictures of the engine. You can see my shroud placed on the case. Notice it has provision for the oil cooler in the stock location. Opinions are divided on how well these work, but I am willing to try.
