Ok, stoppped by the hardware store and bought a 10/32 screw.
Got home and took out the set screw.
I'm really pulling hard and the LPR still won't budge. I've tried a few times but just want to make sure I don't damage anything.
Here is the pic of the bottom of the frame.
So going from left to right:
LPR set screw / air passage (loctited) / not sure what that is / frame set screw
So should I just keep trying to pull the LPR body out?
