You are both correct. These are an overlay that will inset into the groove in the original vents. I should have them back together this weekend. My vents and my Nitro are in the paint shop now getting paint mods.
Jonrs, I wish I could churn these out and give you a set. A lot of hours go into each one. The perforated stainless is $30.00 a square foot. I'll post the 'how to' instructions this weekend with pics.
HEMEEE, I wish we could get others to participate in this thread. Some new ideas would be nice for a change.
LOL! Thanks anyway!
Good fun just guessing. I look forward to the DIY post as I have been looking at doing something with those myself. I was thinking about making them actual openings, with a cool looking cover (Like yours).
