Carvun F60 Dual camera car DVR GPS How to modify for 16mm 12mm lens

Carvun F60 Dual camera car DVR GPS. How to modify to hold a 16mm or 12mm lens or any other size and replacing the standard T mount with a more stable and more commonly available 4 prong mount. This video was filmed with my L3000 720p car DVR as it is better quality than my normal camera. Due to a corrupt file 5 seconds is missing right when I stick the mount to the DVR but you get the idea. Stupid MOV files.
