Looking at it from the "front" of the vehicle.....The tall latch is the secondary (or safety) latch. The small one on the right, with the bevels, is the primary latch.
There are 3 springs on the latch. A circular one is for the primary latch.
The other two springs are straight springs. One for the secondary latch, and one for the release lever. If the circular latch is broken, you will have trouble opening and closing.
