I could be wrong about this but I think their were bolts permanently attached to the door hardware. They were intended to extend through holes in the arm rest and held in place with nuts. You need to take the door panel off and see what things look like as the previous owner may have removed the bolts. As an alternative to an arm rest, the GTA's had a pull strap which you can still buy from various European (not sure about Spruell or Centerline here in the states) vendors.
