Thanks 3B but I need dinemsions. The ones I have look similar to the ones I ended up getting in the mail yesterday but they're about an inch smaller in outer diameter. Most importantly, the shoulder that goes through the frame bracket is 1.5 inches and the new ones came in at 1-1/8 inches. Nobody stocks them up here so I have to order from the lower 48 and want to make sure I get the right ones this time.
