I'm not sure how your search is going to pan out. If you look at the pinlock web site (Products | Pinlock.com) they don't make inserts specifically for Zorax lids. I can't find anything equivalent from other manufacturers, either - even looked on aliexpress.
If at the end of the road you can't find a pinlock to fot, you might consider a foggy mask. Here it is - Foggy Mask - Respro® - you will find it cheaper if you shop around. It's a big faff to get them installed in the right position, but once in they keep the visor clear, and they keep you snug in winter too. And, you don't have to peer at the road through a pinlock, which is nice.
