I did mine, very easy. Just buy some coupling nut with the right thread 10x1.125 but not sure, i dont remember, i'll check and correct it here. Personally, I retapped some imperial size I had. Then buy the according screws about 40 mm long. Screw it in with permanent loctite and cut the head at about a bit more than 1cm. Some flat black paint and there you go with your new extender. I notice that it reduce some weird noise around the helnet. Mine working for long. The best cheapest mod I did.
