E-Z-Eye Glass date stamp / coding for early 50's Buicks


Budd

Recommended Posts

I'm researching replacement glass for my 1956 Super (and man -- let me tell you how happy I am to be actually getting to this point in the restoration). I've contacted a couple of the classic auto glass suppliers, and I'm being asked about overall tint, the upper dark band on the windshield, and what date codes to stamp the glass with. Some cursory research shows it should be "E-Z-Eye Glass" that would be on the Buick, but I'm curious if anyone out there with a early to mid 50's Buick could upload some photos of what their glass date codes look like on the windshield and side plate glass. I found an example of what it should look like and applied some Photoshop editing to match it to what I show on the glass.

I found a nice write-up from the Camaro folks here that does a good job explaining the markings for mid-60's, and I imagine it hadn't changed much. L-O-F meaning Libbey-Owens-Ford glass, PPG = Pittsburg Plate Glass, etc.

Looks like my choices for tint are clear (NONE) or light green (SHADED). I don't know about the dark band on the upper windshield, does anyone else have that? My windshield doesn't appear to have the dark band. Second photo is from my windshield I took out of my car, and if I'm reading the decode right (on that Camaro link), then LV = Mar 1956 which lines up with the mfg date of my car which is mid April 1956.

Al:

I was referring to this chart (albeit listed as Mid-60's). So are you saying that LOF had a different coding scheme for Buick versus Chevy/Pontiac/Olds etc? For my own education, would you mind pointing me to where you are referring to? Everywhere I look refers to "L" as March code, otherwise I would not have stated as such above and certainly would like to find the correct info for our Buicks versus making a false inference.

Hopefully that is coming across politely, as I'm intending -- :)

edit: I did find one reference here for Corvette that shows 1953-1956 being L=January, and 1957 after L=March. Here

So -- if I apply the Chevrolet Corvette information to the above, it is saying there are different LOF codes depending on year in the 1953-1956/7/8 range. The L and N codes are transposed.

Budd - my original windshield had the dark blue band along the top.

E-Z-Eye code is also LOF within the shield, AS-2 NX under the word "plate" - same insignia as yours. All my glass has AS-2 NX on it, except the rear quarters have NUX. My car is an early 55, came out of the Wilmington DE Buick plant if thats of any value.

Can you post what you decide on a windshield supplier - am interested in one that will put the "bug" on and have the right thickness glass. Adding the bug was not an issue when I replaced some of my side glass but one supplier told me he could not put it on a windshield. Currently I have a non-E-Z-Eye windshield in the car and plan to put the correct tinted one back in. Cracked the original one a long time ago while the car was on college duty.

Nice job and thank you for keeping your site pictures up by the way - helped me out.

. . . . .So are you saying that LOF had a different coding scheme for Buick versus Chevy/Pontiac/Olds etc? . . . . .

No.

I'm saying that LOF's glass codes are the same for all General Motors' autos. As you researched and found out, the MONTH CODES were changed somewhat during the 1957-1958 glass production years.

Your chart in POST #4 is correct; your chart in POST #3 pertains to some, but not all, 1957 and later month codes.
