I have a windshield for a 1971 cutlass 4 door sedan that's cracked and the antenna is broke. Im getting the glass replaced but I'm wondering is there any value to the old/original glass? In other words should I throw the old one out. Sorry if this is a silly question. But I've tossed valuable things before.

 

No value for a broken windshield that I can think of.

 

Save a photo of the date code thingy maybe.
