1/24 Brake cooling ducts?

do these exist? I am building the Nissan R390 GT1 with the SMS photoetch kit. There is a ton of detail for the front end and I would really like to get some proper ducts. I have the photoetch brake duct mounting hardware on the car and its going to look funny without a hose coming from it.

I believe this is what you might be looking for: http://www.hiroboy.com/catalog/product_info.php?cPath=25_32_53&products_id=3629

thats the tubing. what I was looking for is the housing that the hose connects to.

I found my old Taisan Starcard Porsche that I butchered a few years ago. I am robbing parts from that to scratch build the duct housing.

the duct hoses I make by wrappingwire around a tube, then wrapping that in teflon tape, then painting.

I supposed I should start a WIP, I am taking pictures.
