I have seen a Unique with a hole drilled thru the 2 x 4 frame behind the radaitor and a 2" pipe installed. They used a couple of small stainless screws in each end of the pipe to help hold the hoses onto the pipe. I made a back to back 90 degree pipe out of two 1 1\2" copper elbows and a short piece of copper pipe. I silver solidered the pieces together and flared the ends so the hose would not slip off. This allow me to go up and over the frame piece and steering rack. A little black high temp. paint and it looks good.
