Title: What kind of dates would you expect to see on glass?
Post by: BGlover67 on February 09, 2018, 06:31:09 PM
What are the current thoughts about glass dates?  How much sooner would the glass dates be as compared to the San Jose date on a 1967?  Are they all about the same (Windshield, side, rear, etc), or were some pieces completed earlier than others?

Brian, All the glass on 6S1568, front, sides, vents, and back window, are all dated January 1966. As far as I can deduce, the car was assembled mid-March 1966 at San Jose. All glass is original. I hope this helps, let's see what others have to say. Denny

Brian in an effort to provide the best possible guess or range can we know then you car was completed at San Jose?  Reason is that there may have delays or issues during one period of production not seen in another.

Thanks Jeff (and Denny).  I actually was inquiring in a general sense after speaking with a friend who is looking to purchase a GT350 from the first week in May.

Still, I would be interested in the dates that would be appropriate for No 26.  It's San Jose date is 10/10/66.  Thank you as always.

Don't have any examples from that same couple of weeks (yours plus or minus a week in either direction) but looking at a slightly wider range during the same season of the year and comparing the year prior (same time of the year as your car and same plant) I can offer the following information.

Dates seem to range from within the same month out to 3 months prior to the build month

For the May car I have dates 1 month to 5 months prior to build month.  Maybe has something to do with other unknown influences such as supply, transport time or supply plant issues that year that part of the year.

Sampling group is small but its a place to start

Though never enough samples IMHO what I did find is that typically they fell into the 1-3 month range prior to the month the car was completed on for this plant and year. Even took a look at the prior year just to compare. Some cars would have one piece of glass that might be out of this range which would suggest that you look at that area or glass a little closer to see what else you can find if your inspecting a car.

Hope this  helps in some way

1242 Ford assembly 2/1/67 has 7A dates on all glass except windshield (ws is replacement Carlite).
Correction - on closer inspection passenger door glass is 6M - vent is 7A.

rule of thumb, look at the dates on the rest of the glass, just use that. seems to be the norm from what I've seen over the years. back glass might be off. phred

Wow that is different all 5 pieces the same date.  First time I've heard of that happening.

Cars I have records of just before and after had spreads have different months around the car

Jeff, now you got me wondering if what I said is totally true.  I will double check and report back if different - what I said is from recollection and will verify. 

My previous post has been corrected. Thanks, Jeff
Kurt.

The only date code I can see on all the glass except the windshield(replaced) is A7

Just so that we understand and I can record this correctly - your reporting that all five pieces of glass have the same A7 date?

Any chance the glass was replaced at some point?  Just had to ask.

See your car was in group 892590  a very different time period and group from #1242 (grp 892573) who reported the same pattern and date. Just thinking out loud

Only glass date codes I can see easily this evening is the passenger door and wing.

Passenger door glass 6L
Passenger wing/vent 6M

SJ 1/26/67

With age and lighting they can be a pain to see - or just be too poor of condition to read. Just for comparison I have the following just for comparison

- A car likely built (lacking a Marti report on it) within the week prior with a PS vent dated 6M
- A car finished the day after yours with PS door glass dated 7A and a DS door of 6M.

I have no reason to believe the glass has been changed.  The car sat from 1979 to when I first purchased it in November 1987.  All 5 pieces appear to have A7.  I will look again in sunlight, but not sure the date will change.

My car has a build date of 3/23/1967. It has the following dates codes on the windows:

Rear glass 7C
Driver's glass 7A-vent 7A
Passenger glass 6M- vent 7A

I'm 98% sure the passenger door glass is original based on the conditions of the interior door parts and hardware!

Was the back glass "SUN X" on all cars? I'm pretty positive it's original too.

Thanks for any clarification here!
Regards Matt

yes, rear glass was tinted, all other not (no tint strip at the top of the windshield either - unless the car had factory A/C.
7A = 1967 January
7C = 1967 March
6M = 1966 December
