I've never seen someone struggle so hard to change a set of heads. It gets really funny around the 7 min mark when he's trying to remove the old heads. Then even funnier at around 10min when the heads slip back off the ramp and he has to separate them again to get them back on.
You know those heads didn't survive. Why would anyone post such a screwup publically on youtube for the world to see?
So the donor drive was still with the original sticker but it was already missing one screw and a number written on the head contact?? :mrgreen: :mrgreen:
