How? Where? Found this custom rod shop in Monroe, LA (cannot remember his name, would have to search long and hard to find it again.) that I called and asked if he did louvers. In my long search, I have found that anywhere there is an interest in Nascar, there will be a shop that does louvers. I removed the hood from my car and threw it (carefully) into the back of my Tahoe and made the 6 hour run. The guy let one of his fabricators do the job. He carefully cut the brace out from beneath the area I wanted louvers and re-welded (TIG) inboard 4". (He didn't even burn the paint when he welded it back!) Then he proceeded to set my hood up inside this gigantic "C" clamp looking press that was used only to louver sheet metal. He measured 3 times before he cut. We all held our breaths. At 13, he said it looked balanced, I agreed. Charged me a whopping $130. Needless, I tipped him heavily. Took the hood back home, chemically stripped the whole thing, and had the body shop respray. This has been about 4 years ago. Just now, I got good photos. My son's camera. I still use a Brownie Hawkeye, equivalent.
