I went there, and tried to order the 2006 reverse gauges, but not sure if they would fit, since they say 2003-2005 gauge, and it also says manual transmission on the ebay link, so....would they fit?
If you want to see the 2005 kit on a 2006, check out my cardomain.
I THINK the only difference between MTX and ATX is the small section between the two pods, just leave that one out like on mine and you'll be fine (I like it better without the center section anyways, it gave a little more contrast)
