For some reason, the un-plated box is cheaper from DSE than it is from TurnOne. DSE lists their steering ratio @ 12.7, while TurnOne lists a 12.1 ratio.
Lee is also back in business if you want a Lee box.

You will need a new rag joint. I'm not clear if there are any differences or not, but the CP rag joint (CLP-RJC730R) is $50 cheaper than the DSE (090205)version. I'm sourcing these prices from Summit Racing.
