Looking for a source for VDO gauge part.
Looking for the cup or hat type red, green, amber diffusers.
Tried Helier and Palo Alto.
Thanks for any response.

That's a tough get. It's either rescue them from dead instruments, make your own or ask a friend who works in plastics(!) to do some for you - or switch out to just flat acrylic which is not OEM appearance but is very easy to procure from amazon, etc. You would probably want to "scuff" them up a little bit with some high grit sandpaper to give them a frosted look.

I had a fellow lister here pour some acrylic ones for me after pulling a mold from a sacrificial one but the final finish work was pretty time-consuming for anything more than just a couple - sanding them into shape and proper thickness and then ending up with the right 'frosted' finish.

on mine, i also replaced the usually-white one with a red for visual continuity - and i put an LED behind it as an additional indicator for another function. they white lenses can be VERY brittle - but so can the red and green ones.

I think mine turned out great but i think if i were to do it again - and originally i had designs on maybe having these done in mass quantities - i'd just switch over to some 1 or 2mm flat, colored acrylic stock and glue them in.

UNLESS someone like @mikey914 and 914rubber would be able to do this in quantity at a reasonable cost? I've wondered where places like North Hollywood and Palo Alto get their stuff...I suspect they have a stash that they are raiding....

Thanks for responding. And the gauge you have is very nice.
Palo Alto is not into parts, but they will refurbish your with new diffusers.
I might have to machine some out of plastic myself.
Thanks again
Jim
