Just download the pdf file from Vans, print it out, pick up a piece of aluminum and cut it. I went to a scrap dealer and got a piece for about $15 and it took about 15 minutes to cut it out, use my belt sander and then the scotch brite wheel to finish it off perfect. I did have a HVAC friend put the 90 degree bend on it for me since I don't have a brake. I wanted my panel a little taller than the stock part and to incorporate the vents a little different.
