Rear Brake Caliper Piston

Rear Brake Caliper Piston
Need a little help, guys. I damaged one of my rear caliper pistons getting it out of the caliper and I need a replacement. I searched the internet and couldn't find the 32mm piston for the 991 rear caliper. The calipers are for a 2014 S, but I believe they're the same as a Base. Does anyone happen to have one, or can someone point me in the direction of a vendor who has them? Thanks in advance

The S models have a 32/32 x30mm pistons while the base are 28/30mm. I just put in an order for two 32/32 caliper rebuild kits which contain all pistons and high temp seals needed to rebuild a caliper (going to offer these now). However it will be two weeks before they will be in my hands.
i can continue to look around for other replacements if that doesn't work. If i find them ill will dm you!

Mike, Thank you for your quick reply. I need one 32/30 S piston. I have everything else. I just buggered one up getting it out of the caliper. Rookie move. I think it would probably be fine, but I scratched the piston surface and I don't want to risk it. If you (or someone) could find just one, that would be great. If not, I'm good with purchasing a kit. Please let me know.
Thanks again,
Chris

Thanks again, Mike. Here's the piston. I'm not concerned about all the damage I did around the dust shield. That should be fine - unsightly, but fine. BUT, I scratched the coating on the piston surface. It doesn't catch a thumbnail, but I can feel it. Valuable lesson learned.

Stick a fork in it; Thats done! Will report back.
Edit: you should be able to cross reference Centric 146.32009 or Stoptech 41.532.0003

The Stoptech part number is discontinued. I keep running across the Centric part, but the compatibility charts list this part number for the front only. They never mention the rear calipers. If the dimensions were posted, I could check them against mine, but they're not.
Mike - am I right that the damage to the dust boot area will be OK once I dress them a bit? Asking for a friend because there's a decent chance several of them look like that.

Im seeing one on RockAuto right now (32mm for the rear) - Centric Brand. I’ll check my supply in a few:
Ok all i have is an extra 28/30 piston kit.
