I checked it out after getting your last posting. The current number to use is just the Q-6-82-0363, that's the bracket and changer together. It goes for about $700 at our dealership, just to give you something to work from. This Q# seems to have replaced both 163-820-13-89 and 163-820-13-89-90, which is a reman part, as you can tell by the -90 at the end. I am unsure if either of these numbers are still available, sometimes they are. I would suspect the -90 part may still be available, but as a reman, they would expect that you have a bad unit to turn in as a core, or else you typically pay a large core charge. Hope this helps, I'm not really much of a parts man, but I can kind of navigate the system (I know just enough to get me into trouble, in other words
)
