Did "Flo-Lite" ever appear on 67 windows?

[Joe R.]

My understanding is that all 67 windows had "Safety" on the left side of the LOF logo, and "Plate" on the right side.

I'm looking at a 1967 door window that looks correct in every respect except that it says "Flo-Lite" instead of "Plate" to the right of the LOF logo.

Has anyone seen this on an original car, or is this an incorrect reproduction?

I don't think that "Safety Flo-Lite" was ever originally used on 1967 Corvettes or, for that matter, any Corvette through early 1971. "Safety Flo-Lite" came into use for Corvettes sometime in the mid-1971 period. After about that time it was used for both PRODUCTION as well as LOF SERVICE for earlier model Corvettes.

Joe R. - Does the manufacturing date code agree with the 66-67 codes? Pete

Joe, Pete:

The date code on this glass is LZ, which would correspond to March 1967 if it were made in 67. Did the date codes ever repeat in later years? That might explain hiow this could be a service replacement that was made after 1967.

The seller has pointed out that in the NCRS 1967 JG, Safety Flo-Lite is listed as being an acceptable alternative to Safety Plate. There is an additional note in the JG that says "there are documented examples of Safety Flo-Lite glass used as early as December 1966."

I'm beginning to think this glass might be okay to use in my April 67 car, although all of the other (original) glass in the car says Safety Plate.

Yes, It is correct for later 67s.

Yes, the code is LZ (March 1967).

YES the glass codes repeat in later years. I don't have those codes here with me on the Road Tour, though.

Funny how we hash these things out 25 years ago and finally get them into the manual, just to forget it all and hash them out again. I have only seen Flow-lite on 67 side glass. It might show up somewhere else, but it`s a fact, Its real. My May, 1 `67 car also has Flow lite.

Yes, the code is LZ (March 1967).

Even though it's obvious from your post that you were talking about side glass, I was talking about the windshield. I don't think any 1967 used "Safety Flo-Lite" for the windshield. I really don't know about the side glass for 1967 but "Safety Flo-Lite" was used for 1968 side glass so it would make sense that it was phased in during 1967 for the side glass.

Hi Joe,

I ran into this issue when I first decoded all the glass on the '67 I'm working on. According to Colvin's Corvette by the Numbers:


This car has all original LOF glass except for the driver door glass:

Passenger vent = Soft-Ray, Safety Plate, Solid Tempered, dated YA (Oct. 1966)

Windshield = Shaded Soft-Ray, Safety Plate, Laminated, dated VA (Dec. 1966)
Rear glass = Soft-Ray, Safety Plate, Solid Tempered, dated VA
Driver vent = Soft-Ray, Safety Plate, Solid Tempered, dated VA
Passenger door = Soft-Ray, Safety Plate, Solid Tempered, dated VA

Driver door = Soft-Ray, Safety FLO LITE, Solid Tempered, dated GZ (April 1967)

This car was built on January 11, 1967 so "GZ" can't be right. There was a lot of broken pieces of the original door glass still in the bottom of the door, so the original door glass must have been broken early in the car's history, and replaced with glass dated the first month of FLO LITE availability, at least according to the Colvin book.

Also this: "The original glass in 1963-67 Corvettes was LOF Safety Plate. LOF Safety Float is a replacement, as are other brands. The only exception was in 1967, which may use Flo-lite side glass." - Adams, p. 184

It seems like if the date is correct for your car, Safety Flo-Lite should be okay. Was Flo-Lite produced at the same time as Safety Plate during 1967? Are there any examples of '67s with "Safety Plate" dated after April, 1967?

Re: Did "Flo-Lite" ever appear on 67 windows?

A further check of Colvin's book shows what I think Terry McManmon was referring to, regarding the repetition of codes in later years. Colvin says the first letter in the date code did not repeat from 1958-1982, but the second letter in the date code did repeat.

For the window glass you're considering (LZ), pages 548-549 (Colvin) shows it could be either March 1967 or March 1980. I did not see any mention of how to distinguish a March '67 Flo-Lite from a service replacement Flo-Lite made in March 1980, or whether they were still using the exact same trademark, logo, etc. on the 1980 service replacements.

Re: Did "Flo-Lite" ever appear on 67 windows?

Yes, date codes 'rebounded'... LZ = either March, 1967 or March, 1980.

Here is an interesting research paper on GM glass, this was about Camaros, 67-69, but also applies to Corvettes:

Hi Michael:

Wow, that is a great article. Those Camaro guys are going to put us Corvette guys to shame!

It sounds like the manufacturers started adding a DOT marking after 1969. My guess is that the DOT would appear on service replacement parts as well.

So, even though the date code LZ could appear on a service replacement window manufactured in 1980 (date codes repeated, as noted earlier), I would expect to find a DOT marking on a 1967 service replacement manufactured in 1980. Other aspects of the marking may have changes as well by 1980.
