Yeah, that's what I was already using for the install.
I think it must have popped out and I missed it. I can look clear through the hole in the release cylinder, and it's not blocked. All that I can see in there is what looks to be some thin spring (but no pill, just a spring - maybe this is what was holding the pill in?).
Anyway, either the pill is laying on it's side or it's out. Either way, I finally gave up struggling with it and put cylinder back on the car.
