Lehner 1950 end cap help!!!

[Hickoryhead]

The heat sink won't work unless I don't understand how it goes on. Do you not put one end of the heat sink between the motor and the motor mount? You just use longer screws? If I am wrong let me know. I am just looking at the picture in the RCM store. That would hold the end cap it self on. The end cap motor mount screw holes are fine. The end cap it self screws into the motor body. Those are the threads that are stripped. Not the mount screws hole threads. I might see if there is enough metal left to make new threads but it looked like the metal was gone so no chance of using a die to make new threads.
