Welcome to the site !!
Maybe do a search in your surrounding areas or farther if need be , for a Motorcycle Wrecking yard , you might have some luck with that .... The only other place (besides EBay) would be (not sure if you are on Social Media or not) is Facebook Marketplace , I am always finding bike parts on it ..... There is also this http://www.oem-cycle.com/
, which is full of used parts and other helpful things
