How do i change my 88 buick park avenue back passenger window?

someone broke my window now i have a hard time putting the new one back on.do i need to take the door panel off completely?

any help would be nice.thank you.How do i change my 88 buick park avenue back passenger window?YES THE DOOR PANEL HAS TO BE REMOVED.I CAN'T REMEMBER IF POP-REVITS HOLD THE GLASS TO THE REGULATOR OR NOT BUT IF THEY DO KNOCK OUT THE CENTER OF THE REVIT WITH A PUNCH AND DRILL OUT THE REST .YOU CAN USE BOLTS AND NUTS TO REPLACE THE REVITS WHEN INSTALLING THE NEW GLASS. THE NEW GLASS DROPS DOWN THUR THE TOP OF THE DOOR. THERE IS MORE TO IT THAN THAT BUT IT'S HARD TO DETAIL EVERY LITTLE STEP.THIS IS NOT AN EASY JOB IF YOU HAVE NO EXPERIENCE.How do i change my 88 buick park avenue back passenger window?Yes, you have to take the whole door panel off.
