Topic: 65 fastback side glass, pls come in

[camp upshur]

Were 65 2+2 door windows made in limited batches?
I noticed an Apr 65 SJ 2+2 with both door windows being 4Js which seemed 'early' (the ww's were both 5A and the rear 5C).
I chkd my side spares, which were also 4Js.
Since then I've chkd a couple of 2+2s door glass: one an Apr 65 with two 5Bs and the other a JULY 65 with both being 4Js!
May I ask if any 2+2 owners could perhaps chime in?
Thanks.

So my October of 64 fastback side glass is dated 4J and my June of 65 is dated either 5D or B, hard to tell which letter

Dearborn May 17 65 Fastback has 5C both sides.

A sampling from my records

5R2174xx    DS 5D     PS 5A
5R2423xx    DS 5B     PS 5F
5R2393xx    DS 5B     PS 5B

Glass gets swapped around allot it seams so we kind of got to evaluate the whole car and its condition to make a choice to believe the glass is original or has been replaced

At least by the first of the year it appears that they were producing the fastback glass on a monthly basis  if the dates above are original and correct to the cars. Would believe that the 4J's were from a donor without knowing any additional information

Chris, 65KGT, Jeff: thank you very much. (This forum is so substantive!)
I felt 4J was too early and it now looks like the glass was being steadily produced.
How I've ended up w 'all' the 4J's is a real head scratcher.
Appreciate it.
Clear (non-tinted) windshields: they too were produced monthly?
