72 Commando, Axle Doner???

I'm lookin at a 72 Commando to be an axle doner for my 80 CJ7.
The rear is a D44, 1 pc. axles, 2 3/4" tubes, 3.73 gears.
The front is a D30, drum brakes, 3.73 gears.
I can't get good measurments cause it's sunk in dirt.
Will these axles make a good swap?
What problems will I encounter?
What I'm shooting for is something that is close to a direct swap, and being close to same width as a narrow track.
Would these be the 30 spline 44 axles?
BTW, it has a running 232, 3 speed, and a complete drivetrain as it was driven to it's resting spot. He's asking $400, but there's no other lookers. I think I can get it for $200 after the seller festers a bit.
All help is appreciated.

You had to do what to fit those little tires?
I'm sure glad I own a CJ!

Pretty good bolt in
Front: bolts in but you will want to use your 80 D30 from the knuckles out to retain your disc brakes. The 72D30 knuckles do not have the casting to bolt the 80D30 calipers bracket.
Rear: When you say your running a three speed I thinking manual tranny right? Just be sure both rears are centered or offset, which ever you need to match your transfercase. This is the 30 spline D44 you want. You will have to relocate the spring perches a few inches wider. You can get these at any speed shop and weld them on. One difference is the pinnion length. I think the AMC20 has a longer and therefore closer to the transfercase pinnion. Just an inch or so. Your current driveshaft will work but check it's ability to expand and compress with your suspension. Also most brake parts, shoes, drums, small parts will switch from one rear to the other if they are both 11inch brakes. Since you will be retaining the D44 brake backing plates get the emergency brake lines from the D44 also. Later years are different in the way that they attach to the brake backing plate but can be made to work if the D44s are cut or busted.
That about all the issues I can think of. I sorta did the same thing with 74 axles into my 76

Should work good. They are narrow-trac width, with the rear springs/perches outboarded.

How's the rest of this donor 'mando? Anything left body wise that you'll be getting rid of? Pics?

No need to move the spring pearches, this is a straight bolt in. I think they even did this swap in an issue of JP. The 72&73 Commando and the 86 CJ are the two bolt in donors for Dana 44's.
