That's an old school way of getting sheet metal to cooperate
The way I see it, it couldn't hurt if it bends, it looks like it's bent already.
I would place the 2x4 or 6 on the left, and hang on the right side until it's even, poco a poco, you will probably divide the gap between both sides so look to drop the latch.
I think it comes up through the core top, maybe you can lower with washers and longer bolts.
