Note that I haven't installed it yet so I can't be 100% sure that it fits although it looks *very* similar when held next to the existing one. I'm traveling at the minute but when I get back on Wednesday I can send a photo of the two and get you exact measurements if you want.
Yeah, that's what I thought as well. The "eye" in the pin is very slightly higher on the new one but I cannot see how that would be fatal but I just might not be seeing something. I may not get mine fitted for a few weeks so let me know in the meantime if you get around to yours.
