Two months later, finally another update!
I decided that it would be easiest to mold the trim ring of the monitor into the dash itself. It would give me the clean look I’m going for and I wouldn’t have to worry about rigging up some kind of brackets to mount the monitor. In case anyone is questioning the weight of the monitor putting stress on the dash and cracking it, it’s not going to happen. The monitor is super light. So out came the dremel once again! I glassed it in, added some filler, primed, spot filled, sanded, primed again and finally plasti-dipped. Came out pretty good if I do say so myself! I left the mini USB port and will hook it up to the carputer when I do the final install.
