IRWIN- the 451 is the SB for the 6-speed.

XFH- Thanks. Yes, since the 451 A2 was listed for AMD applications, I figgured it would not work on my Limited with an auto. I had hoped that there was another (new) supplier out there that my forum and Internet seaches had failed to uncover but it's good to know that the Hong Kong guy might be able to get the 451A that I need. Thanks again.
