Replacing driveshaft

I blew the rear u-joint out of my 72 F250 a couple weeks back, and it took the driveshaft ears off, as well as damaging the yoke. I have been having a hell of a time finding parts since I moved, I don't have my old network anymore, but I think I found what I need. It's under a 74 F250, 2wd longbed with two piece driveshaft, just the same configuration as my 72. The question is, will this driveshaft fit my 72? All I'm looking to swap is the rear half, pull the slipjoint apart, and slide it under my truck with a new universal and yoke.
Were the driveshafts still the same, or did they make some changes?

What are the transmissions? C6, NP435, T-18's?

I need to know this before comparing coupling shafts, as there are pages and pages of them.

Mine's a T18, not sure on the other one. Did they change splines or location of the center support? All I'm grabbing is the rear half or the driveshaft.

1967/74 F250 2WD 352/360 / T-18 & NP435: C7TZ4817BW .. Coupling Shaft / 34 1/16" long / 3" in diameter.

1968/74 F250 2WD 390 / T-18 & NP435: C8TZ4817K .. Coupling Shaft / 34 1/16" long / 2" in diameter.

Oddball question maybe. I've read in this forum a million times that a 360 and 390 are almost identical and pretty much interchangeable. If this is so, why would the truck require a different shaft based on the engine? I can onlly guess that the one behind the 390 is tougher.

Probably the increase in torque. However, my truck even though it is a 360 truck (vin Y), has a 2.75" diameter tube.
I talked with the guy, the 74 driveshaft is the same diameter, but about 2" longer. I'm going to take it and cut it down if need be, I have the tools and talents to make it work.

If the coupling shaft is 2" longer, it's from a truck with a 138" wheelbase, or a different year other than 1967/74.
