D-mag, P7 & hipcc question

[BeachBoy]

Hello, I need to fit a hipcc, or the der weichel driver (??) inside a D-mag, with SSC P7.

I will not run batteries as this will be driven by external power.

My question is, which heatsink/P7 holder would I be able to fit the driver on the other side, or any other method to fit the driver inside the light?

Regards,

I guess I'll have to find out for myself
