You can sell the D35 and go to your local yard and pull the brakes off of a D35 in a ZJ with discs.
If you have an 8.25 you can still do that with the same ZJ brakes or pull them off of a KJ (Liberty).
But if you're really hellbent on swapping axles, I'd swap in something that has the same bolt pattern and not another D35. If you're going through all that work, you should put in something that is better.
So basically ZJ brakes, KJ brakes, 8.8, full KJ swap, build up an 8.25.
Even if you stuck with the D35 you have in there (assuming that's what you have), I would swap the brakes from a ZJ. Wouldn't bother cutting of spring perches, buying new perches and dealing with all the mock up to have an axle of the same shitty caliber.
