Original TR6 glove boxes were made of pressed fiberboard, and like many mine was warped and crumbling. I replaced it last year with the modern ABS plastic version, and it's a good improvement in all ways but one: the new version doesn't include a mount for the interior light.
The original glove box had a pressed steel mount riveted on the side wall so the light socket could snap on. Stupidly, i forgot to save the light mount when i threw out my old glove box. I decided to just make my own, and upgrade to an LED light in the process.
