Throw up a pic of the broken tabs.
Just a thought, did you try putting the LED in both ways (insert, test, rotate 180*, insert, test) I thought one of mine was fried until I remembered LED bulbs can't go in backwards like the OEM bulbs.
Just a thought, sorry if you already tried this. Also, if you can't find a second gen and the part is the same as I am thinking I have a Junkyard near me with some second gen Foci. I could possibly pull the part for you if it works $$ wise.
If you can't wear it out, burn it off
