Kevin,
If it's a Coupe/Roadster (as opposed to a 2+2 California Coupe), then the latches to hold the top down are at the front and on the sides by the side windows. 1 pair in the front and 1 pair on the sides.
The Coupe has a single pin at the rear that's unique for the model, as well as a pair of latches at the front.
