I bought my top with glass window from Auto Tops Direct, they are the same top as GAHH(same company). I used their ebay site because it had free shipping. I used Collins Custom Interiors in Colleyville for the installation. The cost for install was around $500 which is very worth it to me since it can be a pain to do. I had this done two years ago and the top still looks perfect.
