Is there another size slider or did someone change the guide bar on this thing?

Hi I bought the 51-32-1-938-884-M295 part off of Pelican Parts to fix my window problem. The previous slider broke on the regulator arm that connects to the rail to 'guide' the window. I tried to install these and they were too wide and too thick? I don't know why they don't fit properly into this guide. I tried inserting it into the other one close to the bottom of the window but it fits fine. Is there another size slider or did someone change the guide bar on this thing? Please help asap!

Talk to one of our parts specialist at 888 280 7799 and maybe they can help. Maybe someone installed a different year door and that's why the parts don't match
