Well my 99 K2500 had the airbag delete pocket, it was actually very useful for the passengers. It held gloves, cameras, phones, etc very nicely. They actually have a 1/2 round edge and slope inward, so things stay put fairly well.
If I do a OEM color it will be grey or neutral. I have considered charcoal like my 02 GMC has (which is nice) but i do also like the lighter grey.
Thanks for the compliments. I'm honestly SO close to tearing the entire truck down piece by piece in the next year or so, just waiting on a house so I have a permanent space to do it in.
As far as seats, I'm planning on sticking with the 95+ style seats. So much more comfortable. I do think I'm going to buckets this next go round though.
