Gordon I think you're looking at my spare tire mount/rear k-member. I made that three years ago out of some aluminized exhaust tubing. The oil cooler bracket is a bit more modest—if no less holy.
I did spend about 5 hours today finishing that part and cutting/forming the duct down and out the bottom of the car such that the fan will be drawing all it can through the oil cooler.
Getting the fan to lay down in there under that bracket was a trick. But we're down to a couple a speed nuts and some rivets now before moving on to plumbing. I also strung a wire through the holy tubing to run to the fan thermostat. I'll make that the hot lead with an inline fuse and take power right from the starter lug.
Opening up that nice clean pan I put so many hours into took a deep breath.
Initial fitment was too tight...
Working it on the car like this was a bit fiddly as well. I ended up using a pry bar as a dolly to hammer the curve into the forward opening. Rough, but workable and good for airflow; I'll smooth it out later.
Cut the sides out.
Socked them in with screws for fitment...
Holes seem to line up OK
Generally speaking this installation will not be a focal point of the engine bay.
