LI DUAL INSTALL
I spent this past Saturday in California helping another member install on his late model VW GTI. Was not easy due to honeycomb grill which was also sloped and the tynes were also down-sloped. We ended up just doing a brute force cut, slowly carving out enough until the heads would lay flat, then hot glued them in place. A little messy, but some black enamel paint or black plastic matching trim should make it disappear into the background. The metal trim from LI was not useful in this case - nothing to mount it to. Total time was about 7 hours. Ugg!
The heads should of been mounted another row over toward headlamps. I marked the cutaway with sharpie, but the owner hacked off starting on the wrong row, so we ended up mounting the heads about 2 inches away from my original target. (Not my car, so I let him do the actual cutting)
Cutout for 1 head:
