I have their number in my contacts, usually if they can't sell it to you, they can at least tell you if they have it.
If you find out they do have it.... Look up an authorized retailer to order it for you. Their adaptors are usually around $20.
@onthehunt526 I will try to call if I can find the number, the universal one looks nothing like what I have. UNLESS the numbers are printed on the ferrule and the adapter is a separate part where the "castle" fits inside the ferrule. (I am beginning to think that is what happens)
