i think I've reached the point where I'm just going to have to try things to see what works. Whether that's using a shim or placing the specialty track on top of the 4 tabs, we'll see.
As a side note, this is a 3472. Ross showed 2: one a 3472 and the other a 3482. I'm not knowledgeable to know the difference IF there is one
I checked out the doors and to me they are properly placed. Here are some images.
A closeup of the doors (i have 2 images and include both in case one is clearer)
These next 2 images show why I think the door cannot change position. Before that let me add that I tried to see if I could alter the positioning and I could not. These 2 images show that the bottom of the door frame has 2 tabs. The images show them squarely in place tight up against the floor of the car.
I appreciate those that chipped in to offer suggestions but it seems like my 2 listed above are the conclusions I've reached.
As always, THANKS = walt
