Update:

The last reply I made in this thread that linked you all of the plastic nylon clips I believe should fit that I said I was going to check with the company.

Okay, this is what has happened thus far:

I did make the order for those clips, they arrived, off the bat they pop in place in the holes when you're attempting to put the trim panel back in place, the problem with these clips though is that you need to make sure you align them precisely when lining them up or they break RIGHT AWAY.

Another thing, the head of top of the nylon clip that you insert in place into the panel trim itself DOES NOT just slide right in!!! the plastic between the top and the groove that is slides into is just too big in size. What I had to do to make it "work" was to take a pair of pliers, grab the top of each clip and slightly add some pressure to "crunch" its size down abit so that I could get them to slide in place, even then while trying to do it, you have to use all your might to "get them to push through" and STAY in place..

This is just not the right clip but I was able to manage to get them to stay in place doing this route....

They can work if you're careful and do it right...

Unfortuntely, the top ones on the panel trim BROKE because I didn't align them perfect but all the bottom ones made a perfect fit, now it just looks like the top portion of my panel trim comes down until I found something else that I was able to make work BETTER:

I did figure out a much easier way to make this work that may be easier than using these clips and are actually much more reliable... You will need to do a little bit of work but you will get it once you're done and you can buy it now at your local auto parts store.

They are made by Dorman, buy the NISSAN/INFINITY Door Panel Retainers, part # 963-081, they are gray plastic nylon clips with thin black looking seal gaskets attached, they do come apart but I would keep them intact as they pop into place MUCH EASIER. Each plastic package has 4 of them, you'll need to buy 2 of them to complete your panel trim, maybe buy a third incase you break a couple...

These clips will pop into place perfectly into the holes. The only problem where you need to do alittle EASY work is getting the top of the heads to slide into your panel trim.

I plan to make a HOW TO with a VIDEO tomorrow showing the clips & what needs to be done so its a PERFECT fit!!! so look out for it! I'll update this thread with it
