First year Hustler deck adjustment question

[Hustler27]

I have a first year hustler raptor and I'm wondering if anyone can help me with how to adjust the deck height so that it is more even. I was recently in to the dealer to et replacement parts that had rattled off, but it appears this is another part of the original model that was done away with. None of the current raptors have the same parts holding up the deck. I have a series of small pieces that hold the up left side of the deck, but I can't figure out how to get them to do more than just hold up the deck. I need to raise the left side a little. The replacement parts helped to stableize the deck during typical mowing conditions, but I'm finding when it turn, it creates a visually obvious uneven cut.

Thanks for any help.
