have a 4 bow, 69'w x 79'L canopy. cant find replacement fabric.
That is because there isn't one available. The reason is because each bimini top (fabric) is created for the one frame it was made for. The process of making a bimini top frame is never the same from one shop to another, or even one fabricator to another. So to achieve the optimal fit you have to have the correct frame to canvas, or you have a sloppy fit. Fabricators know this so instead of hearing back from the customer or having a return, they choose not to make them at all for other fabricators frames. It's just not practicable. So unfortunately you will have to have another piece of canvas made and create a whole new bimini top to your existing frame.
I hope I have answered your question well! Have a great boating season.
