The Tenaxes are a weak point whenraising/ lowering the roof. The sequence to use is....
Raising...they are the last bit to fit.
Lowering....they are the first to release.
Mine broke when this sequence was missed. They were plated brass so not the strongest. It is possible to drill out the bit stuck but takes care. You then plug the now empty hole, drill a pilot hole and screw in a new fitting. You MUST do a pilot hole to reduce the force needed to screw in the new part! If not then the new part could easily break as you apply the force to screw it in. I simply replaced mine with two screw versions with the "button" part in the correct place over where the originals were.
Masking tape as a buffer, position the replacement cheking level to ground, mark where the holes are, drill slowly, get/make a gasket for between the fitting and panel to protect the paint, fix with stainless screws.
Then get into the habit of correct sequence for raising/lowering!
