Fenderwells are discontinued. And no one is reproducing them. Basically all 81-87 Regals,both 2 and 4 doors use the same wheelhouses. There was a specific set for the 84-87 turbo cars and 81-83 turbos but you can use the NA wheelhouses in a pinch. Here are the differences. On the right side the NA car had some raised bosses to mount the ESC module, the 84-87 turbos didn't. On the left turbos(all years) there is an indentation on the front to clear the stock air cleaner that was bolted to the frame rail in that area, you can use a NA in its place if you are running a K&N or non stock air cleaner. All left sides have the bosses to mount the PS reservior and cruise servo even though the NA cars never used them.
