New Classic Industries items

I understand hardtop and convertible glass is different but is there a difference in the 68 and 69 convertible glass? ClassicIndustries website says the door glass is for 69, but does not mention it would fit 67 or 68

look at other sites selling glass. But I’m pretty sure 68 and 69 A-body glass is the same.

I think 1967 a-body has different attachment to mechanism.
