So you actually have a slant back, are a well known member here and only took the time to write a sarcastic response instead of looking at my pictures and offering insight into what might fix a problem? I didn't expect that on this forum.
BLK is an awesome member. He has also made it clear that he removed his Slantback ages ago.
I have no doubt that either something is out of alignment OR something is bent. You need an assistant. You need heavy magnetic handles to lift the hatch up and out. You need to measure and realign.
These tops open traditionally or rumble seat fashion. Attach to the pins closer to the rear hatch and see if she will show you how to realign the pins to the frontward latching mechanism. The striker pins are all adjustable. Maybe a few slipped due to looseness. Mine were out of alignment, so I realigned the striker pins to make things perfect. These vehicles are hand made. If the hatch is not original to your rig, you might have some massaging to do to make it fit. Don’t assume that just because the hatch came with your purchase that the hatch is original.
There are differences between some hatches, with some being more square. Ensure you have the correct hatch. I am not sure about the different hatch iterations. I have an old M1025
Less close up pictures and more pics from 6’ away might help us help you.
Good luck
