Finally managed to start my projector retrofit! The lights are too big for the oven so got a heat gun (about 20 years old!) on the go and managed to get one headlight open after about an hour! Will do some more over the weekend and see how it looks before I seal it up!
Just a quick preview of the lens and shroud in an approximate position...loads more to do but its a start! I've only rested the projector and shroud in place and the only way was to put it on the worktop upside down so the photo is a bit strange with the wall at the bottom!
