Swapping D44a axles, anything funny about swapping their brakes?

So my son cracked his 2002 WJ's D44a's aluminum pumpkin on the bottom when he slammed it into a rock. I have a replacement D44a axle but it has drum brakes where my son's D44a has disk brakes. I'd probably be ok with just using the drum brakes but they didn't come with the drums themselves, I'd have to buy them so I'd rather not since I have a perfectly good set of disk brakes on the original axle.

Swapping between disk and drum is easy on a standard Dana 44 which I've done on my TJ, but what about this c-clipped D44a? Is it the same process? Is there anything more to the swap than unbolting the drum brake's backing plate and bolting up the disk brake assembly?

No advice to dump the D44a and go for a "real" D44 is needed here, you'd be preaching to the choir and I got the replacement D44a for free. Thanks in advance guys.

Yeah, I cannot think of any D44a that would have drums, even if it came from a ZJ (which will not work if this is going to a WJ).

Also, the WJ axles are not c-clipped like the ZJ. Just 4 bolts on the outer flange of the axle that retain the shaft, like your TJ D44.

*edit* unless the rotors are removed and what you are seeing is the e-brake set up?

Oh yeah cool!! Now that I think about what I saw, you're absolutely right!

I just glanced at the axle for a split second as I passed by it late last night (it got delivered by a friend while I was at work) and now remember the brake shoes I saw were too small for drum brakes. Yep, they were the parking brake shoes I saw. I just need to get some rotors for them now, what a relief. Thanks!!

Crap I finally had a few seconds to look it over more closely and it needs both the calipers and rotors. I'll just transfer the brakes and rotors off the old axle, no big deal. So far as as I know, it's off a WJ.

A quick look will be on top of the center section will be a mount for the A-arm (for WJ).

It's a 2wd GC with street tires, he knew better than to take it where he did since we have the TJ for offroading. He won't be doing it again or he'll find his *** in boot camp.
