Never ever give up on a Delrin Simplex derailleur.
I would be looking for an adhesive that bonds acetyl type plastics, usually a two part system.
I have one that has typically cracked, I was going to bond it then bore two holes and run a long 00-90 brass machine screws into it (decent hobby store item), if I recall there is room to the inside of the M5 fastener.
I'm using some old very thick Panaracer stuff. Has worked well for over two years now, securing some loose floor tile in my bathroom.
