lol i don't fancy buying a whole r32 light for a part that i don't think will fit 
you can have it half price as the glass is broken, £200 posted

like tim says best bet is speak to depo, or get some plastic and repair the hole, if you get two layers of plastic the same thickness as the back, cut one the size of your hole (32mm), then glue a bigger piece to the back creating a lip, then glue the lip to the light back. then cut the correct size hole.
