I did the full swap after grenading my diffs last year. The 44a will bolt right in, no issues except gear ratio and the drive shaft. The pinion neck on the 44a is longer than that of the 35, therefore your driveshaft will be a bit too long. Just get it cut to size after the axle is in.
wheelintj - it isn't the aftermarket support that people look at for the 44a swap, it's the all around stronger axle (minus the aluminum pumpkin). Truss the 44a and you're good to go.
