Decoding my RPO codes

Not sure where to post this, and I don't expect anyone to do my homework for me so I did as much research as possible... A few people have seen some of my options and said they are kind of uncommon / rare... I'm sure many of you have them, but would this be considered a highly optioned vehicle or run of the mill GN from 87?

Also, when decoding I saw some things in the description that said "nc and aow" Would someone mind filling me in on what that means?

I spent a bit of time going through and looking up every single RPO code. Some info I found was very specific, while other info was vague. If I have anything incorrect or that someone could elaborate on?

This is for my 1987 Buick GN with T-Tops...

That's kind of what I am looking for... I was curious if any of the add on's at purchase made the vehicle rare. My GN has quite a bit of rust on it... Drive train is 100% solid though. If it had anything that made it stand out and seem kind of rare, I was going to restore the body back to show... if not, I was going to buy a roller and just transplant my drive train. I figure I'm looking at roughly 60 - 70 hours of labor taking care of the rust. So I was weighing out my options.

Just curious?
Do people really pay extra for a grand national if it has certain options that make it rare? I cant see how a moonroof or ac or power antenna or digital dash would make it so much more desirable than the next? Is that just me?
 
They all had A/c. If it is an LC2 it got c60(a/c)

unless you are the original owner , realize we are thirty years in and things get replaced and/or added. Jack it up and spin one of the rear tires. If the other one goes the opposite direction you don't have a posi.
with that t-type you should also have the g87 and gu6 for the 8.5 axle and 3.42 gears.
