I would suggest giving one of the below a try. The first two I found on Amazon. The Grey Pneumatic I found doing on Google using "thin wall socket 22mm" as my search criteria.
Sunex 2622 1/2-Inch Drive 22-Mm Extra Thin Wall Deep Impact Socket
Performance Tool W32926 1/2-Inch Impact Drive 22mm Thin Wall Socket, 1/2" Impact Drive 22mm
Grey Pneumatic 1/2" Drive x 22mm Extra-Thin Wall Deep
