Chain Guard for 52T Sprocket 390 4T

[MoonBeamer]

So I just put on a 52 Tooth sprocket and as I expected it is too big for the stock chain guide. I have been searching but I can't seem to find a new on that hangs down lower or any type of Extension bracket. Does anyone know what aftermarket one will fit with a 52T rear sprocket? If so do you pics?
