Although it's showing only the 2007-present version of the Tundra, I recall Code 3 offering a hook kit for the previous generation Tundra. I want to say that this was a kit model that was shared with another vehicle (perhaps a Ford). If you can find out what that kit was, maybe you can try FedSig's equivalent.
Also, I wonder if the hook kit for the Dodge Dakota would be a possible solution?
