I'm in the same exact situation. Bought the kit from Cruiser Corp in late August and I have the same problems with the rear shackles. I was also sent two "B" rear springs and have a lean to the driver's side. I'm guessing that I should have received an "A" and a "B" to prevent this. I sent this into Julissa at Cruiser Corp and this was her response:
Thank you for the pics and all the information.
I do apologize for the delay, I am currently working from home!
I can either go ahead and reach out to ARB but because we do not stock them here, you could also contact them, explain which side it's leaning more towards and they would be able to provide you the plates you need. They're not included on the lift kits as they are not always needed. Again, I can absolutely contact them, just need your details of the lean and possibly a couple of pics to show them as well.
I reached to ARB yesterday to see what can be done and will post here is I'm able to get a resolution
Matt
