Photo is from my 39 pu to help visualize, not sure if car has same latch. The front piece rotates with the handle, the background piece is spring loaded. Like mentioned before try pushing down, in addition to unloading the latch it will help keep the front piece clocked on the handle shaft so it will unlatch and open. At least that's what I did with same problem. Once open you may want to disassemble blend out the wear marks and adjust shaft nut so latch turns with the handle. Good luck, hope this helps!
