Brembo Parking Brake Kit

[Eep]

Hi, we have a 2001 996 Turbo with Brembo off-road brakes from the 996 GT3-R (6 piston fronts, 4 piston rears, fully floating rotors). The car is street legal but for the fact that it doesn't have a functional parking brake. I've seen a kit for the Brembo Gran Turismo brake sets, but only for the Dodge Viper and Acura NSX. We could fabricate our own mount to use one of those, but obviously if there's an option that doesn't require that step we'd prefer it. Does anyone know of someone selling such a kit? (I checked Pelican Parts thoroughly first)

Thanks!
