So I've been searching for a few days for a replacement swing arm bolt for my 85 200x. On most sites they are discontinued, and the ones that aren't want $50+ for them, even eBay has used ones for $45+... Does anyone know where these can be bought at a decent price (or perhaps someone parting out a 200x) or maybe a bolt from another trike/bike that works? Or is there any reason why I couldn't use a normal grade 8 bolt? This would be my first time replacing one so I haven't had the opportunity to look at one up close.
