All of my elevator CA hinges on my LT-40 failed also. It started in the middle and then the outside ones failed. A cheaper fix is to use either 20lb fishing line or dental floss. I drill 1/16" holes on both sides of the CA hinges and criss-cross the line (up one side, down through the gap, then up on the other side...repeat to next 2 holes) and CA each hole as I pull the line through. With this method, you only have to fix the hinge that failed instead of removing all of them to fix the middle ones.
