Same old top vs channel problem

[flouese]

I've searched this forum and read everything I can find. I've searched YouTube and watched every video I can find and still cannot find the resolution to get my top to seat in the channel. All the videos show this flap of material at the leading edge of the roof and a support frame with a fastener of some sort . My frame does not have a spot where a fastener of any sort would go. Is the "flap" the piece that is sandwiched between the sliding clamp? If so, how and where do you attach the elastic? Same question for the frame; do you just wrap the material around the frame? A good clear picture would help me immensely. I just wrapped up installing a new top and want it to work as designed.

Thanks for your patience.
