Was it a used or older mdt chassis sitting on shelf? Or both brand new. You can hollar at
@MDT_Josh as well. There is a chance we could have made a clamp to tight but On the initial batches of MDT the rails were slightly different than spec from what I understand. Let me play around with a clamp at work tomorrow and see if I can find a solution for you specifically just to get everything rolling and get you where you want to be whether anything is off with either product.
