Q: my car is a 1999 xs model would glass from 306 meridian 2000 model be ok both are 3 door hatchbacks

A: I think so. It is true of many model years with Peugeot. However, an AUTO GLASS shop in your area will have a book of replacement part numbers. See if the part number is the same for both years. I'll do the same here where I live and report back later today.... OH YES! If you are taking a window off an old car, make sure that rust and time have not loosened the glass from the rubber/metal bar at the bottom of the glass. This is the reason that most windows come loose and fall down inside the door. TIME AND RUST.
