Ha... I just played this game too on a 99!! Closed door and neither handle worked. The window was stuck down so it was easy to come down to the latch from above with a long rod to push down on the latch mechanism that the outdoor handle's latch rod usually pushes down on. It's the vertical rod for the outdoor handle directly above where that inside red arrow is pointing. Same latching mechanism but different pressure point. I think I am saying the same thing as @RichLo was saying about that rod #7, but even if if that rod was still in position, it should be able to be pushed down with more force than our crappy outdoor handles can do.
Do the early doors have a door vent under the latch? Super easy to work the latch out through there if so.
Thank you, I was wondering where that outside handle rod went. Like I said its just flopping around now and I didn't see where it came from. When I get the door off I'll try to take some pictures for future readers and explain how to rebuild a door easier than what we are dealing with.
