I have an 88 lesabre sedan with crank windows and there is a white clip inside of the track on the window that broke.. its the clip that connects the lift arm to the window.. I went and bought a new clip at a glass place it appears to be exactly the same as the old one... I've never replaced one of these before... I have the door panel disassembled and I need to know how to install this.. It appears it just presses in.. but when i tried it with asmall C clampit didn't want to go.. so i stopped before i broke something... Anyone know anything about this????

 

Does anyone know where i can go to get an answer to my simple problem????
