I'm close to getting Norwood's details current!
I needed to replace a cracked front spoiler and when removing it I remembered spoiler Stielow used on Red Devil and Jackass. I did a little research and head scratching and found a piece of 18 gauge in the garage and started measuring. I already had the OEM replacement spoiler in stock.
Overall I'm happy with the results and it appears to have reduced the operating temp about 10* in our cooler climate.
