Ok, while you were posting I was measuring and taking pictures. As it turns out it is really hard to measure up there, but that socket is 2 1/2" tall and it
almost slides in there.
Those are poly mounts and I'll warn you that if you put the grease on that comes with them you can easily make them 6" in diameter and 1" tall, long before hitting the torque spec. Been there, done that, and you could just keep cranking and watching them squish.
I had to pull them, thoroughly clean off the grease, and then put them in dry to get to the torque spec.
