Technical Chevy glass windshield ID HELP

Can anyone advise how to identify the make and model of as Chevy car from the stamp on the windshield which is called a "bug" I have 2 windshields I think one is for a '56 and one for a '57?????
Number 1: E-Z-Eye
SAFETY LOF PLATE
AS-S JX
SOLID

Number 2: SOLID
SAFETY LOF PLATE
AS-2 I X

Thanks - I'm thinking it's a long shot.

 

Measure the center of the gl***, top to bottom. 55-56 is different than 57, 55-56 has the same gl*** in a 2 door and a wagon, but I'm not sure about 57. I can look when I'm back at the shop, but Google could answer you quicker lol

 

@chevy57dude @427 sleeper or @Johnny Gee probably know exactly

 

All 55-57 gl*** is the same for sedans and wagons. Hardtop, convertible and Nomad is shorter. Same for Pontiac.

 

I stand corrected. Because the 57 did away with the cowl vent it is an inch longer on the bottom.

 

Don't quote me on this, but I think it has something to do with the slope of the gl*** being different on the '57's. I could be COMPLETELY off on this and thinking of something else, though. Somebody around here HAS to know for sure... I think.
The AS-2 IX gl*** is a rear window made in June of 1955.
Not sure what the AS-S is. It was made in May of 1955 though, according to the JX code. Windshields usually started with an AS-1 code.
Pic's of what you have would sure help a ton...

 

Need a damn gl*** guy!!

 

Yeah that's what I was thinking, if he thinks that one is a 56 and the other is a 57, the taller should be the 57, I believe anyway lol.

 

The curve at the cowl 55 56 same 57 different. Height, sedans tall, hardtops short.

 

Thanks to all - I hadn't thought they could be possibly be rear curved gl*** - but the center vertical measurements are 17" and 18"
Measuring the front of the windshield on my '57 is 18" so that agrees with what I am reading.
The Investigation continues.........
I'm going tot stop by a local auto gl*** place this week.
