Okay here is what I am thinking of doing. I was thinking of using the fiberglass top as the basis of a soft top build. I have decided though to simply start from scratch and build a metal frame work similar to a canback system. Something that can be sturdy enough to have a roof rack mounted on top. It will be removable intact as a whole just like the fiberglass top. My canvas of choice will be old Army surplus pup tent halves with convertable style plastic windows sewn in. The top will be basically permanent, but the sides will be able to roll up i.e. canback. For the rear I plan to have a removeable bar for the snaps at the bottom of the rear flaps. I have talked to a buddy that does upholstery and he said the material should be fine and he has a spray on treatment that will make it more waterproof. Hopefully I'll have it done by next spring.
