Those rear lens screws are a pain aren't they, fairly sure my integrale has some stainless screws in place of the plastic headed ones, but that could be in my spare light units

Interesting the "new" ones weren't much cop, guessing they were the ones listed on ebay recently? I was tempted to get a set just to have as spares, glad I didn't on hearing that.
Wonder how hard it is to make some? A mould could be made using a screwdriver and some suitable sleeve...
I too am looking forward to a Y10 meet up at some point
