Aluminum Framed Windows (replace vs repair).

[rwells36]

My 2001 vessels' window seals (glazing) has succumbed to UV rays and proper fitting replacements are not to be found. The glass itself needs replacement and I want to stop the leaks.

I am faced with the decision to replace the glass using the existing aluminum frames vs replace both glass AND the frames. The frames are designed such that the glass floats on a bed of rubberized material.

The window frames are OEM (17 years old). Any guidance is appreciated. I've got 3 panes on the helm and two quarter panes (port and starboard). Thanks in advance!!
