Actually, NO ONE (except you) will ever notice -- esp if you paint them matte black like Razith suggests. Trouble is that now that you find it bothersome, it will always attract your eye to it and devil you forever.
I'm thinking about maybe just drilling a series of holes rather than the slits -- although your idea is very ingenious!
BTW, how did you fasten the grills down to the dash? It looks like the grills pulled the dash down pretty well, right?
Did you use those spring loaded toggle bolts like you use for hanging pix on drywall?
It was fun getting them down in and then slid over thru the notches
I had to cut the notches with a hack saw blade (bare blade bent down by hand cutting in half inch movements) pulled some muscles i haven't used in a while along with cricks in my neck fighting the rear view mirror & windshield
But its sits pretty flat just off center from where I drilled the holes
Flat head brass bolts
The weapon of choice lol
