Help identifying Lego bricks from a picture for a Geocache I'd like to recreate a Lego design I've seen for an ammo can Geocache - its a box that opens with a hinged lid. I've found the parts for the handles (CLAMP 1X2) and hinge pieces (PLATE 1X2 W/SHAFT Ø3) on the top but I'm really struggling to find the large flat plat with hooks on the right side.
If you can help identify this particular piece I'd be grateful. If you have any idea what's on the right side too or any other bricks I need then suggestions are very welcome.
Thank you!
The flat plate with hooks, on the left of the image, appears to be Tile, Modified, 3 x 2 with 2 Open O clips
Without an image from another angle, it is hard to tell what the connection on the other side might be - it could be Plate, Modified 1 x 2 with 2 Open O Clips (Horizontal Grip), or perhaps a pair of Plate, Modified 1 x 2 with Clip on End (Horizontal Grip), but it could equally be something completely different.

After a quick Reverse Image Search, I found this set for sale on Geocaching.com with images of other angles, including the Bag of Parts - and this model appears to use a pair of LegoPlate, Modified 1 x 1 with Open O Clip (Horizontal Grip), instead
