I'm hoping someone has been down this road. On my 86 CUCV, the button on the door handle suddenly disengaged from the mechanism. I opened it up and could see the little latch bar dangling. I was able to shove it back into the hole it goes into and it works for now, but there is nothing really holding it. It appears to me there may have been a little clip or something originally, maybe now rusted away. But I have no idea what the part is, or, if I had it, how the heck I would install it way back in the door cavity. Anyone?
