Hi Phil, thanks so much for responding.
The tray for the 11 is different in that it doesn't have a distinct corner to show the placement of the SIM. I used the logical match first and it didn't fit snuggly so tried a different position. Either way it doesn't slip smoothly into place the way other SIMs have (this is not my first transfer) ... basically when I slide the tray in the SIM pushes out.
I've already checked out the link, it doesn't answer the question :(
I'm concerned about how much force to use to click it into place - I'm just concerned about damaging the SIM.
