Possibly Selling A-833

I have a A-833 out of an A-body that I am considering selling. I think its out of a Barracuda, but not sure. It is a cast iron case, 23 spline input shaft. The input shaft is rusting, might be able to be cleaned up, or might need replacement. None of the gear teeth are chipped or damaged, and there is no rust inside of the case. Asking for $400.00 OBO +shipping. I also live in AZ, and this sucker is heavy, so shipping might be a bit steep. Pick up could be an option as well.
