Nice
Nice job Ben.
There would be no way in heck is disassemble the nozzle to get trim on.
If I haven't said it before I have big hand with a vice grip clamp.
I'd put my nub by the hole and push keep pressure until it went in.
If hole goes through whole headlight hood I'd use tweezer type tools pus through the hole and another tool on the other side pulling it through.
