Jim Bounds (Co-op), in one of his Daily Pose, wrote about a second latching problem. It turned out the outside edge of the pin plate was too wide, not allowing the door to make the second latch.
Ha... found the page. You might check this out.

Thanks. I actually read that article. Initially I thought I might have to shave the new plate because I assumed the pin was to far inboard and that’s why it wouldn’t do a 2nd latch. Turns out the pin actually sits 1/8” more outboard than stock pin. So jaws not reaching is not the problem. In addition, the new and old plate I have both sit flush with the edge of the first channel on the frame. So the door would just hit the frame/channel if I shaved the plate edge.

From the marks on the new pin I believe it’s hitting the latch frame. As the pin goes into the latch jaws they latch down for the first lock. Not a problem because that area is wider. However just passed that the frame of the latch narrows considerably and that’s where the second latch is activated. At that point the pin barrel needs to hit both upper and lower jaws simultaneously or it won’t move. It looks like the new pin is hitting that upper narrowed area putting more force on upper jaw instead of equal force on both jaws. Therefore the jaws will not push in and latch. We are only talking about 1/16” to high but it’s enough. My original pin actually engages the secondary latch albeit with some extra force. I believe it’s because it has rubber bushing wrapped around the pin barrel with another bushing made of thin metal with a gap wrapped around the rubber. That allows just enough movement up or down as it’s pushed through narrow section thus allowing it to push both secondary jaws simultaneously. Sorry if I didn’t described this clearly. In other words The factory designed pin allows for some misalignment by being flexible. The solid pin does not. So I will be elongating the outboard holes In order to adjust the striker plate and pin downward. The inboard holes are factory oversized and don’t need to be elongated.
