The coupler part # CA5100B measures 9-1/4 inches wide and 8 inches tall where it attaches to a standard a-frame. The narrowest part of the angle of the coupler is 2". I have attached a diagram to show you the dimensions.

How tall is the coupler? In other words what is the size of the rectangular tubing that can be welded inside the coupler? You have shown the angle of the coupler and the width of the inside but not the height. Thanks

There typically aren't any part numbers stamped onto the trailer spindle that can be used for identification. There are however numbers stamped onto the hub most times which can be used for identification. The TDE46210 tells me you have a 3,500…

The 22210 part number you provided is actually the part number for the trunnion end which Reese no longer offers separately. But the replacement 800 lb spring bar IS available as part #RP22225. A hardware kit is also available as part #66014.
