hi, your looking for a 20mm two cell driver I think (measure the diameter of the driver or apperture it sits in).

not sure about fasttech but I would try to get this driver in there tbh.

I’ve used this driver a few times and it is a very nice driver in my experience.

Thanks a lot!

Use the existing driver as a contact plate by either desoldering everything off or my preferred option of taking a heatgun to it and flick off all the parts as it comes up to temperature.

This way you can use the cheap 17mm drivers like the Nanjg 105C.

you’d need a dummy cell to run a nanjg, that’s a two cell light.

oops! Didn't see that.

disregard my comment Manos778

its not a bad suggestion, just use a 65mm long 5/8 copper tube with two endcaps soldered on and sanded as necessary and your away.
