You need to make the hole a little bigger with a dremmel and get rid of the notches for the lens to sit flat, but yeah it's very similar.
It's just opening the lens. I can't close the oven door with the headlight in as it won't fit, and leaving the oven door open will loose too much heat. I'm not buying an oven just for this job (even if it is a scrap one), and apparently I can't use a heat gun.
This is looking less likely by the minute
