Thanks for your question. This is an off measurement. Are you measuring from metal to metal, not including the plastic pieces on the ends?

Yes I was measuring the channel only not including the plastic pieces

Thanks for clarifying. In that case, your balance will need to be custom made. Can you tell me what the stamp on the channel reads? Can you also tell me how many you need?
