Yeah, I took the old one out already and tried to 3D print a replacement, but it's not really strong enough for a full pull and I skinned a finger pretty good when it let go. I did flip the old one over so the one side that's still good is pushed down instead of up, which is a little easier on my hand, but figured I'd just suck it up and get a new one at this point. I swear I saw a metal one years ago in a picture, but I've never managed to find anything like it. Looking at the original though I think the plastic is probably plenty tough. I have no idea when or why mine broke since I bought it that way. Had a feeling the 67 one was probably just uniquely styled, nice to know any of the later ones should fit as well.
