Does anyone know for sure where I can get the proper female TEE to bring three of the stock Rx7 brake lines together ? I know I can cut them off, slip a SAE 3/16" male fitting over each end and double flare, but where can I just buy a metric TEE at ? And I assume these fittings are 10mm ? Am I correct ?

thanks

 

I know they are out there, but I'm having one hell of a time finding this Tee, let alone a coupling.
