I have been doing some research on this glass...as far as plant codes, dates..thicknesses...etc.
For those of you who have Bird glass, please post the following.
Date of your build found on cowl tag.
Found on the glass is etching denoting origin/plant of manufacture, date, thickness. Will be found etched on side.
Also include front, back quarter window supplier/manufacturer information. Include if you have clear or tinted, or tinted windshield only. This information can be found on the PHS if you have it.
