If I were your friend I'd e-mail Arrieta and explain to them what happened and what part(s) you need---they are good about standing behind their product. I recently needed a new striker for my 14 year old Model 570, I e-mailed them, they sent me two at no charge...took about a month and arrived via 1st class mail in my mailbox here in Wisconsin.
