I know it's an old post but just found it and thinking about doing it. Is this Akorn hinge on a 22? What is the hinge part number? Are those just regular washers as shims? Would you still recommend it? Thank you in advance.
I don't see why not. My Akorn is closer to diameter to my 22.5" WSM then my 18.5" WSM.
Without measuring I think it splits the difference around 20" and with a bigger radius I think it should fit just fine.
