Have a 1982 wooden narrowline Anderson bay window that has two crank out sides. The glass is 3/8" insulated.

One of the side windows has a crack and the glass is fogging.

Rather than spend $142+ for a replacement window (p/n 0517320) consisting of the primed wooden frame and glass, I'd like to remove the insulated insert and replace it with typical window glass.

Help on how to do that appreciated. Do I remove the trim that looks like glazing and pop out the insert, are the 1/4" plastic plugs on the interior of the window of importance.... where to begin?
