2010 g37x coupe

Snapped the bottom slide pin in the rear left caliper bracket and can’t seem to find a new one (the bracket). I have the 330mm rotors and all the brackets I’m finding that say they fit my car are for a much smaller rotor. It has a part number on it of 3584. Anybody have any leads on where I can find one? Any help is much appreciated 🙏.

 

Thanks for reaching out!
It would help our master armchair parts personnel if you could provide the year, trim pacakge and if its a sedan or coupe.
