I wouldn't try gluing anything, you might get it down into the motor and then you're screwed on that gauge. I've got two clusters that I'm stripping the green off the back and putting LEDs in to sell. One has a slight blemish on the face and that's the one I'll be experimenting with. I'll definitely do a thread on it, I'm sure there's other guys that are tired of not having needle swap options. But, like I said, I don't have a truck to test if the newer motors work. I don't see why they won't, The only difference I can tell is the needle pin size.
