Installed the new tumblers, return spring, and retaining 'washer' (silver, with tang, seen below) in the door handle, BUT the latch arm (gold-anodized, seen below) only fits in THIS orientation, due to it's tang.
Impossible,...won't fit in the door, and the shop manual shows it oriented toward the front of the car,...

Any idea of how these lock/latch parts go together properly? Perhaps it's the wrong arm,...
I have not pulled my passenger door apart to check what's in there,...but it has tumblers, and may still be assembled,...
Thank you, Todd.
