Door Striker Location/Dimensions?

I recently replaced one of mine with a repair kit that I picked up at Carlisle: replacement metal with a lip around the outside and the cage for the captured nut on back. It came with a great set of instructions. you cut out a square on the car, put the repair piece in from the back and weld it in place. It worked great, but I can't remember the name of the company. They also sold reinforcements for behind the door handle and new gasket material for the underside of the air cleaner lid. Anybody know the company???
