Chuck,If You have a torch take an old flat tip screwdriver at least 3/8s wide and bend it about 1/2 inch from the tip at 90 degrees ,than to open up the track put the newly made pry bar into the track and gently rock the handle up and down at the same time You're moving it thru the pinched area ,than you will not pinch the other side and the pressure will be on the track it self ,some times You can find a small pry bar at a tool place but it's easyer just to make one.
Good luck,Pete
