Who has best/ worst vert tops out there?

Robbins makes one of the best and as far as I know is the only one hat has the correct shaped rear glass for the barracuda. I had a friend years ago buy a top from them and the glass was not like the original. He contacted them about it and sent them his original which they used to mold the correct ones.

I looked at Robbins' website. It specifically states that the Barracuda convertible back glass is smaller than the original glass. Also doesn't show the vinyl material used for the top. Looking at their top materials page, it appears that the "Bison Grain" is the closest to the original 68 material. Its time for me to order a couple tops for my 68 verts. I was hoping to find original style material and a correct back glass. The small flat rear glass I've had on replacement tops before doesn't look right to me.
