Ideas for leveling heads when using 3M tape

[hussein]

So that method doesn't work as well in real life as it does in my head. I ended up being off center so one was sticking forward more than the other thanks to the curve of the bumper.

The whole reason I went that way is because I didn't have a drill with me. I picked up a drill for the rear wires, so I revisited the front. I put two screws through the bracket I was happy with, then used it to re-position the second one. I am finally satisfied with the way it looks.

On the rear I went with VHB tape. There wasn't enough length to use the bracket and I didn't have a saw. I will make a thread with pics soon.
