I just replaced my center support bering and as you I was confused about the two different bearings being sold. I ordered both and returned the one that wasn't just like the bad one. "Appears to me" that either will work for automatics or manual shifts. I found one that advertised for standard tranny, $23, and used it and returned the one that advertised to fit all Crossfires. However the A/T was more robustly built. "Only" took me four days to get it changed and put back in car. LoL. My U-joint splines were rusted solid into the front part of the driveshaft and eventually had to pay to have it separated. Don't forget to grease the splines and check both the flex discs for excessive wear.
