Hello all! It’s been a while since I have posted due to some health issues but I’m back on my 300 restoration. The soft top that came with my 300 had a perfectly flat glass rear window. I am having a new top which I got from Robbins installed right now. The installer said the new window had a curve to it and was a bit taller than the one that was in it. Can anyone tell me if the rear glass window was originally flat or came with a slight curvature to it? TY all in advance… looking forward to getting back to posting my progress!
