Kayline went out of business in 1999-2000. Another company bought their assets, but I don't believe they ever got it all going.
As far as I know, there is no service or parts available for their products.
You could try a company like Collins Brothers Jeep (they love old stuff!) to see if they have anything on the shelves, or any suggestions.
Personally, I love the advice that you need to buy a new soft top! (kidding!)
