More folks will respond, I'm sure, but I'm aware that the rotisserie rings are loose-fitting by design, so fire control becomes a little bit more challenging. In looking at your pics, it doesn't look off by much (although red looks worse than blue)? If it's close, you should be fine, especially considering the loose fit of the ring. Another thought is whether your lid is no longer perfectly round after what I would imagine would be countless uses? I'd trust the rotisserie ring to be more round since it's new - if your lid is no longer round, it won't sit well on the ring. Many on here have ways to get the lid back into round if that's the case. Good luck!
