K30 would be a 205 AFAIK
Someone here will verify that though.

I stand corrected..... How rare is a K30 outfitted like that?
rare...
I've seen two late 70's GM K30 4x4's, that had 400 small blocks, and TH400/NP203 drivetrains factory,both were the old style Holmes Wreckers ,with short wheelbases...have seen a lot more 3/4 tons with TH400/NP203 setups than one ton dually's though,but they evidently did exist..
Around here, a TH400/NP205 setup is real rare in the older trucks..most of them with TH400's had the NP203 in the 70's(even though I guess a NP205 WAS available then?)..,or the NP208's in the 80's ...
I'd guess about 95% of all the usual 1/2 ton 4x4 pickups and K5's in the junkyards,and most of the 3/4 tons I've seen here had TH350's with NP205's,or NP203's..pretty rare to see any TH400/NP205 setups here,only a few dually dump trucks I saw with SM465's manual tranny's had NP205's, and I look at a LOT of junked trucks in my area!...so if and when you DO find one for a TH400,they want a kings ransom for it usually..
They seem to have sold more TH400/NP205 drivetrains out west and down south, than here in my area...

I had just never seen that configuration before. Down in TX I can find 465/205 or TH350/203 all day long. Some of the others are a little harder to come by and cost their weight in gold but I had just never seen TH400/203 and hadn't even considered finding that combo in a 1 ton. I am surprised that the General put that T-case in any 1 ton application regardless of tranny configuration. Thanks for the info
