Fan Housing Strap

[Schmuck69]

I have the sharpbuilt 911 cooling kit for my type-4 and have one simple question that I can't see to get the anwser to.

Where do you get the strap to hold down the fan housing to the base?

All of the pictures that I see of the sharpbuilt kit and others all have what appears to be a two-piece strap that is different from the stock 911 strap. Someone throw me a bone here and help me out.

PLEASE,
