The stock box is pretty much your *only* way to go. There is no direct replacement. Those running other boxes involve new fabrication of the mounting as well as adapting the steering column, which being the case, it really doesn't matter what box you choose to replace it with, same amount of work involved.

my advice, if you're on a budget... search the bone yards for a stock replacement with less wear and tear on it than what you've got. I've got replacement boxes used for the price tag of $50.
