help for my girlfriends neon please

hi im new here so please bear with me. my gf has a 98 plymouth neon and she wants to lower the back windows so they go all the way down. she has manual rollers. i would like to know if this is even possible before i go and take the door panels off. i will be back in 3 hours to ckeck back. thanks in advanced

Look at the width and height of the window and look at the width of the lower part of the door that the window would have to go into. I don't think its going to fit?
