124 Window regulator guide jaw install help
 

My passenger front window has been slow for some time. It finally got so bad that the motor would overheat and cycle. I took the inner panel off and found two plastic parts in the bottom of the door. After using the search, I have determined that the part is the window regulator guide jaw. Will order new one but have not got the slightest idea as to how or where to install this guide. Any guidance would be greatly appreciated.

Thanks in advance, Roscoe
