Tapping the channel down is probably the easiest to try. I've never seen a w/s channel like that. It looks like someone hack welded it to the frame. There's supposed to be threaded holes across the top of the w/s frame to mount a channel. The fj40 top had a bead sewn into the frt of the top and it slid into the w/s frame channel from the side. Best Top offered a channel to attach to the frame with a slot in it similar to a jeep top. . The top had a plastic strip seen inti the frt of the top that slides into the channels slot. Your configuration is similar to bestops but with a lot of weirdness going on. Below is a pic of a FJ40/Kayline channel, which probably won't work because you don't have enuff material.
