Will This Fit A 72 4x4??

[72longbed]

Found something today that I couldn't identify. This was in three separate pieces: 1. a TH400 transmission marked 1979 3/4 ton Suburban, 2. a transfer case crossmember that had a large aluminum adapter plate bolted to the front of it at a right angle to the bottom and a skid plate on the underside, 3. a transfer case that had the speedo cable input coming out of the passenger side of the rear tailshaft housing. This transfer case did not look like an older NP205, it had an aluminum output shaft housing? The owner of these parts said they were all together at one time?

I don't know if this helps any but the truck that these parts were supposed to be going into (1971 4x4 frame) had a Dana 44 front axle with plates/caps over the hubs rather than manual locks??

I'm trying to figure out what the heck this setup is. Could it be stock 1979 3/4 ton Suburban 4x4?? Will this setup work in a 71/72 4x4 frame?

Any help indentifying these parts would be great.

Thanks,
