Just went through this in my Eagle. Once you get the 1 3/4" fascia board removed you can remove the four screws that secure the board covering the water tank. Once that board is removed there's plenty of room to reach in and remove/replace the broken carriage bolt.
Thanks for the tip, so this allow one with normal/large hands to access the bolt?
I did replace the eyelet with the new style of bracket from FWC that used a larger plate and 3 bolts to secure a piece of aluminum angle and am told that they basically don't fail. It looks far more confidence inspiring than the eyelet so I'm hoping to not have any more trouble. Thanks for the info, though. Steve,,,,,
