The brackets are actually bolted in place but the captivated heads do look like large rivets. They are held in place with the penny washers you see here and nylock nuts. I have used a spring washer and a standard nut as the plate I have fitted stopped the nylock nut from fully engaging.
The body is quite new, 2014 spec and was only fitted 3500 Mls ago due to the old girl being belted up the backside by a range rover.
I used to suffer from lots of split bobbins but since the heavier 1.5mm exhausts were fitted the bobbins have stayed intact.
The body does vibrate an awful lot around the rear mounting. The front mounting seems much more rigid.
The split is broadly horizontal and just below the bottom bolt hole. The split does not emanate form the mounting hole. Local dealer is talking to Morgan so we will see what happens.
I think vibration is the problem. I just hope it's a one off and maybe a bad pressing. For a truly effective repair I would drill additional support holes in the bottom corners. Will wait for Morgan's response before any further mods
