Thanks for posting! With a winged top attachment and non-winged bottom attachment, it appears that your balance will have to be custom made. Please take a look at this Custom Channel balance Order Form that I have started for you and fill out the rest of the information. One of our representatives will be in contact with you shortly thereafter.
