I have two pair of rear targa latches that are restored by powder coatind and installing new springs and clips.
The early pair is on top with the smaller bumps.
Early should be 70-72. Please compare to what you have.
Easy ID can be made by checking if a nickle or a quarter fits between the bumps on the latches. A quarter fit on early and a nickle on late latches.
$100 a pair plus shipping? .
