11.65 dia rear brake kit for IRS (Roadster)

[Sundowners]

Hi. I’m looking for a 11.65 dia rear brake kit (rotors, calipers) for IRS. This is the kit that will work with 15”wheels. I figured I’d ask, thinking someone might have updated their brake kit and have these lying around. I need a set for my 289 FIA.

Thanks
Brian
