Blue Bubbles for Rallye Gauges

Does anyone know where I can get the blue plastic bubbles that cover the lights in the Rallye Gauges. I know I saw some company selling them a few years ago.

Pretty sure it was PG Classics offering them.

I just sent my tach to instrument specialties, the blue " lenses bubble" is cracked, when asked if he had any he told me no he would epoxy it. So maybe they aren't available at this time
