Just like Jim says... Soft - ray is what most people call tinted. But tinted glass is very dark, almost solid blue. I am fairly sure (90%)? that 68-69 glass for firebird is the same, except for bird glass. That would also fit '69, but technically not be correct. 'Maro glass is the same size and would interchange. 'Maro's version of bird glass is called Astro-Glass. (for '68 only as well) I have two or three sets of soft-ray door glass from various '68's. A couple of pieces of bird glass, but not a pair. I have one soft-ray and one tinted bird glass. Coupes and convertible door glass is the same, but rear quarter windows are different for 'verts.
I am heading to Door County in August and could bring a piece of glass if you still need it.
I used to be indecisive. Now I'm not sure. I feel like I am diagonally parked in a parallel universe. 1968 400 convertible (Scarlet) 1976 T/A - 455 LE (No Burt) 1976 T/A New baby, starting full restoration. 1968 350 - 4 speed 'vert - 400 clone (the Beast!) 1968 350 convertible - Wife's car now- 400 clone (Aleutian Blue) (Blue Angel) 2008 Durango - DD 2008 GXP - New one from NH is AWESOME! 2017 Durango Citadel - Modern is nice!
