On the front of the top where it rolls over and goes down the A posts, is there a seam? Or is it one piece of material. I bought a new top from Johns Classic Cougars in Michigan. Probably next week will be installing it and after taking it out of the box to let it lay in the sun (hoping to get wrinkles out) I am wondering how it will fit. Appears the back window is cut out and I will have to lay in a piece along the bottom of the window. It is cut straight across the front. I don't recall any seams in the front where it goes down the A posts. Is there? If so does anyone have a picture of this seam? Thanks Harv.
