Hello appearently i had trouble with my last thread. I have a late 90s model N5A. I had to completely gut the helmet. All thats left is the leather shell. Does anybody replace new impactcaps and the metal ring on the inside of the helmets. I contacted cairns and i am aware that they are the only people that are supposed to replace that stuff but i know for a fact someone out there has the supplies I need. If I have to send the helmet to cairns it would only be a couple of dollars more to just purchase a new helmet. Thank you for your help.
