I had already broke the pins by the time I did the video. The video is the 4th, or 5th time opening that thigh open. I think the pins would fail before damaging anything else, but if you want to go the extra step, just get a thin hobby knife in there and cut the pins.
Edit: Just to re-iterate, I am suggesting the nubs as a repair to fix the leg if it has the issue of not staying on. If your leg is fine, do the "upgrade" at your own risk.
