That's actually a really good idea because I've been trying to find and 11/32 Cobalt bit to drill a hole in the stainless steel coupler I purchased. But the pain is a oddball size how did you get a 3/8 bolt to fit snugly in the factory pin hole? I would have to probably tap the shaft and just make a smooth bore hole in the coupler because trying to tap stainless would be difficult.
