That's great Marty and exactly where I assumed too. The louvers do not cover the indentations.
The way mine were drilled, they were placed right on top! The templates were not far off that either.
I do know that the two lowest holes are 3-1/16" apart and both are 4.5" from the 1/4 panel to rocker panel seam.
The front most top hole is 9-5/16" from the lower holes and the top rear hole is 9-1/2" (+3/16") from the lower holes also.
I have found it best to mark the two lowest holes, then mark the uppers and not worry too much about actual dimensions.
How the louvers sit in relation to the indentations is far more important.
Thanks again Marty.
