Hi @Rikki ,
I'd recommend you open a CARE ticket for spare parts here: https://www.behringer.com/brand/behringer/support#googtrans(en|en)
Once you submit your ticket you should get an auto-reply email. If you don't, check your spam/junk folder. That email will tell you that someone will contact you within one business day but be paient as that is more like a week or more these days.
You need them for air 12 right. We can help you if you still need them.
