how to fit handbrake to porsche brakes?

[tom'72]

Here's my setup

stock vw bug hubs machined to fit porsche 996 GT3 discs and calipers.

Now the problem is, I have no idea how to make the handbrake work with this setup, I'd prefer not to go with a hydraulic handbrake if possible.

Does anyone have any pics or helpful info on how the handbrake setup works on a 996 GT3.

Any help is appreciated really.
