I did get some off a guy on eBay, not sure if still available, he made conversion grub screws to your needs, is the Nash M5? Can't remember but had the 2ba for the Cygnet short pivot arms.

Great alarms, the only thing missing for me is drop back differentiation. I've had them since they were released, have seen hundreds of nights never had a single issue. They were a fine replacement for my RX digitals which in my opinion are the best alarm ever released
