A-Bodies are notorious for broken latch strikers at the doorjambs. This car came with a dog leash fastened to the racing bucket seat, which hooked over the door lock button in place of the normal latch mechanism. While this retained the door, it wasn't up to Mopar Muscle's safety standards, and would never pass tech at the drag strip. A-Body strikers mount through a hole in the jamb sheetmetal and screw into a thick floating plate retained by a spot-welded cage. Eventually, the backing plate will work through the non-reinforced jamb, and the whole apparatus will collapse. Luckily, we found the original threaded backing plate behind the door panel.
