The vent windows and separator are showing their age and it seems like it would be easy enough to replace the rear quarter glass and vent with a 1997 solid glass piece. Other than repairing any bi-metal corrosion when performing this conversion, is there anything else to be aware of?

I intend to replace both sides when I do this. It should be a straight-up "rip and replace", as far as the rubber and window is concerned (I would think). I just don't want to find out too late that the replacement 1997 glass and rubber won't fit in a 1998 opening once the vent and glass have been removed...
