Spent the last two days fabricating the mounting system for my pusher fans. I used .120 6061-T6 angle aluminum. I made a jig that represented the final design and checked figment. From there I cut all the pieces and fitted them to the jig. After removing the mounting system from the jig, I fit it to the car. A little trimming and it was good to go. I disassembled everything, polished all the pieces, then reassembled them using black 8-32 flat head hex head screws. After everything was tightened up i tested them.
