Drivers Side Trunk Hinge - In the survey the highest San Jose sequential numbered example with the driver's side hinge with the "cage" feature was -5R09C142xxx
The lowest sequential number example with the driver's side trunk hinge without the "cage" feature was - 5R09C1508xx.
A difference of about 8,000 units most of them being unrelated (to the subject) coupes.
Like the design change of the trunk lid spring and the retainer the use of the cage appears to have taken place at the same time during production.
Should mention the painted/installed electrical wire clip placed over the end of the trunk spring in the picture above. We will be getting to that detail later.
