I made very good experiences with Canti sockets from Brake Stuff.
They are a bit more expensive, but are made by very good quality (stainless steel or high strength Aluminum) and with excact dimensions! You will find detailed drawings on there website.
They also offer the 3-Hole Plates for the brake return spring on V-Brakes e.g. Shimano XCR V-Brake M960 a.o..
