Sunset Porsche in Oregon has the 9X7 short shifter (997-424-983-00) for $343.85
They had both the 9X7 and 9X7 short version in stock when I contacted them this morning.
They had mine shipped and sent me the tracking number less than an hour after I ordered it.
This is definitely faster than normal, but the service and prices from Sunset have been excellent, every time. (I have no affiliation with them, other than buying parts from them about 10 times over the last 18 months).
