Whats going on fellas,

Well the time has come for me to replace my seats. The plan is to run a Bride Digo II as the passenger using the type MO rails, item number BRI-N107MO (US Passenger for the coupe) and run a carbon Bride Stradia II as the driver seat. I'm at a loss with the rail type. I've had one vendor say its supposed to be the LR, which isn't available even using the z33 part number, and I would have to order another MO and modify it. I've also seen another member use the RO type rail but that's not available either. Is there another rail that I can use that fits the Stradia and bolts to the driver side? I've tried researching but maybe I missed something. If someone can chime in and help me out I will love you forever.
