Got a question about swapping a transfercase between 4WD GM trucks, Blazers, Suburbans, etc.
I was kind of hoping someone out there might know this - so I don't have to find out the hard way.
I have a 78 K5 Blazer - 350 V8 with a turbo-350 auto trans. It's a farm snow-plow truck. It has lost 4WD. I never paid close attention to it until now. I see it's been converted a long time ago, from full-time 4WD to part-time. Lockout hubs added and a conversion kit installed into the transfercase. It now does not work. If I really jam on the transfercase lever - it will pop in and out of 4WD, but won't stay there. So, I'm looking for the easiest fix. This is a farm truck and will never go on the road.
I have many junk 4WD trucks in my fields with many extra transfercases - so my question is about what might fit.
I have many 80s to 90s trucks with New Process 205, 208s and 241 transfercases. The problem is this. GM puts different splines in transfercases depending if for HD use or LD use. I know the following for newer partime transfer cases - e.g. 205, 208, and 241:
Transfercase splines to fit a heavy duty four speed manual (SM 465 cast-iron with granny low) are the same as for a turbo-400 automatic. Shaft is 32 splines.
Transfercase splines to fit a light duty four-speed manual overdrive (New Process 833) or a light duty turbo-350 or 700R4 auto are 27 splines.
Now, I've got this truck with the full-time 4WD NP 203 transfercase mated to a turbo-350 trans. Anybody have any idea what splined shaft it's going to have?
I'm also wondering if there might be a way to pull the lockup guts out of this 203 and maybe fuse them together someway to make it 4WD forever?
I'm just trying to figure which will be the easiest since this truck is basically just a farm truck. I was considering taking the plow off and just sticking it on to another truck - but that's a lot of work too. Especially with a Fisher plow that requires a belt-driven hydraulic pump mounted on the engine.

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
