Snap Tonneau....can I make my own?

[lukbrw]

I have a 76 stepside. Back in the day when we first built it, we had a custom snap tonneau cover put on. Of course the snaps are put right into the bed. After 15 years the vinyl cover is shot. Seems to be no one does vinyl around here, but could I make my own? A local store sells the snap rivets and gun for tarps, would it be possible to just get some vinyl and go to town?

The other option would be to have a shop that does custom canvas boat covers with snaps.

But if someone has done their own vinyl top....send some info.
