18 louvers punched(nicely done). Louvers are 3 in wide on a piece of sheetmetal 26 3/4 long by 5 wide. I purchased 4 sections of louvers from Canada; used 3 sections on my 32 Henry cabriolet deck lid. Yes, I know the decklid does NOT match the current body colors; told the body man any color will do, just wanted them painted. $65 shipped CONUS—-no PayPal, NO Texts. Postal m.o. is acceptable.
