I took an idea from another member and locked down my tonneau cover back edge.
However - I failed to take into account that I have a ladder mounted on the tail gate that interfered with the left latch. It's driving me nuts that I had to reposition the left latch and have extra holes in the bed now. May have to order a new box to clean it up again. The extra hole is going to forever bug me.
But - you can't pull up the cover with the tailgate closed now! You'd have to have something to really pry and break things to get into it.
I started with latches from Amazon, cut off part so it would hook over bars at the rear of the cover.
I attached the latches using 5mm rivnuts. The trick was to cut away the bed liner so that the rivnuts would sit against the steel of the bed and not sit proud of the spray-on bed liner.
I tried just drilling and setting the rivnuts but they didn't want to work with that thickness and I didn't like how the flanges sat out and held the latches out from the bed. So I got creative.
This is the right side. I used the existing hole (enlarged it) for one of the rivnuts and drilled for a second one.
One of these holes was a factory hole I enlarged for rivnut -
This is the left side. I originally tried to center it like the right side was - making two new holes. Note the holes in the latch are not centered in the latch body itself so to center it meant moving the holes back. Thus the rivnut you see here - but when closing the tailgate the ladder on the tailgate hit the latch. So, I had to remove the latch, move it forward and set two new rivnuts, so now I have one that shows. I may try to get a black plug to cover it as it's driving me NUTS! Ugh.
I had to tip it a bit as in the end I did end up using the existing lower hole but to clear the ladder mount had to move the top of the latch forward a bit. Didn't want three holes down there (existing from factory and new ones). So the lower screw is in the existing factory hole like I used on the right side latch.
Aside from my mega-screw-up, here's how I got there otherwise:
Latch hook arrives closed - I cut part away. I later had to trim away even more to clear the bar and fit between the cover bar and the cover itself.
Below is how it ended up after trimming more to fit over the bar.
I also drilled the mounting holes a little bit more and countersunk them for the screws I used.
And the holes - I drilled and then cut away the bed liner for the rivnut flange to sit down against the steel bed.
The tools used - drill bit of course for the rivnut size being used, then I used a spade bit to start cutting the bed liner just a little bit, then a Dremel stone to finish cutting into the bedliner without enlarging the hole in the steel of the bed.
Since it was not always easy to get the bed liner cleared out perfectly concentric with the hole in the steel, I also have a really small cutting bit for Dremel I used in my drill to get it rounded and centered over the hole in the steel.
Now the kicker - the rivnut tool assumes the flange of the rivnut will be up against the tool itself. In this case it's recessed a bit into the bed liner, so pulling the tool handles first wanted to pull the rivnut back out of the hole until it contacted the tool.
To get around that, I put this part in my lathe and cut it back a bit so it would reach into the hole in the bed liner and contact the rivnut flange. I created a shoulder on this part of the rivnut tool so it could reach into the hole in the bed liner and contact the shoulder of the rivnut.
