slimline

We have a couple Oceanic Slimline regs, and the little plastic exhaust port covers pop out and go missing. I'd sometimes discover them at the bottom of the dive bags and put them back in, only to have them fall out again. Now vanquished through time, I was wondering if any Scubaboard hobbist...

Parts needed. I am looking for a dive rite canister light lid, this would be the 2.5” variety. Does anyone have an old lid lying around? If you have it attached to other spare parts or even broken light head with a lid this is fine also.
