Who and where should i buy a new top for a 69 barracuda

My brother had a 66 Sport Fury ragtop with a plastic rear window. He was told to unzip it before lowering the top. My 69 Fury III ragtop has a glass rear window and I have never unzipped my window to lower the top.

Btw - I found my top on ebay 15 years ago for 100 bucks. New old replacement stock. I'll never find a deal like that again on a top... It is not the high quality as Legendary is, but for 100 bucks I decided to try my own install. It really wasn't THAT hard to do. It's not perfect, but doesn't look hacked either. I should have used a heat gun to stretch the sail panels out better. Live and learn. I plan on doing my own top on my 68 B'cuda when I get to it next decade.
