I'm sure you can get an insert/square plate surround but that sounds a little to easy to be true, I contemplated fitting a starlet square plate surround but wasnt sure how much work was needed
Mines are currently unscrewed as I unscrewed them for some reason?? Idiot, but I'm just living with it at the moment I'm sure I'll need the dash out at some point and I will do it then, I have had it out 3 times this month!
Buy a march boot, or convert it. I'm sure there are many ways to do it tbh but not glued up on any of them, but I'll keep an eye on this as its something I want to do!
