Nope, trans and transfer case are from an 84 K30.
I don't think you could ever get a TH400/NP208 together from the factory.

Shows what I know, I thought all the M1009's had TH350's.

It's definitely a lighter color than the seats are. I guess it would be grey, Being in a blue truck with a blue interior might it have made me think it was blue.

It's all from that same truck, I didn't grab the headliner as I didn't really want to cut it up to try putting it in a Blazer.
I said grey/blue because I wasn't really sure if was blue or grey, I do know that it is absolutely perfect.

I'm sure it would, though I'm highly doubtful I could install it in a K5 without it looking like a hacked up mess.
