I'm told in the 70's Gm offered 3 types of glass pack
No air con, option was clear or light shade of green...
Air con... Option was above with the addition of a darker green....
Anyone know this to have any truth and is there any glass experts on here ?
I have an aftermarket shade code on my glass which is B-F-67 its important for. Me to know if this is a light or darker green shade....

 

You again? I thought you went to sleep!

Below is the Delta 88 page out of the 1973 Dealer's Specs book. It's a bit hard to read, but it is readable.

Option A01 at the top of column 2 shows "Windows - Soft-Ray Tinted" for $49, and that includes a tinted windshield. Or, option A02 is just the tinted windshield alone for $35.

These are the only mentions I can see regarding window tinting options, and there seems to be no connection to whether or not the car has A/C. Normally, if one option requires another, it will say this, but there's no mention of "AO1 required" accompanying either of the A/C options ("Four Season" or "Comfortron").

 

Thank you... I think that pretty much confirms they only do the one shade of glass...
