Did you fibreglass it in or? I plan on trying it out on a spare headlining.
Also, hows the plasti weld going?
nar no fibreglass, just cut out the hole so its a tight fit around the sunglass base. it slots in at the front and then kinda clips in. you will need to bend up a bracket and screw that in to the front rail above the mirror, theres 2 screw holes for a roof mounted rearview mirror, use them to mount the bracket, then you'll have to drill 2 holes in the top of the bracket whichyou need to line up to the 2 holes located in the sunglass part when the flap is down. thats the hardest part to line up.
plastic welding is going good, got the hang of it and used it to do the screens
