Actually, that's about all there is to it.
It's just 8 T's and 4 pieces of 1/2 in PVC water pipe stuck together as shown (1-1/2 inch lenghts of pipe hold the T's together without gaps). I had to put it across a 2x4, weight the ends and hit it with a heat gun to get a bend into it. I used 3 plumbing hanger straps at the stock mounting points. I am still working my bending techinque to get the tubing bends around the headlights right.
