Not the exact one he uses in that video, but the adapter piece he mentions looks like it would fit fine on that upper portion where the locking nut for the bowden tube screws in.

Also, if you're going to be doing mods like that, I would highly recommend the Vyper Community Edition firmware.

It gives you many more options than stock, and you can compile it yourself to allow much higher nozzle temp limits if you swap to an extruder and heating element that can hit 300+ degrees.

Also worth noting that switching to a V6 style hotend means your longer threaded nozzles for the V5 on the Vyper will no longer work, so you may want to grab some extra nozzles with one of those.
