The diffs out of the new emaxx will fit any maxx bulkhead. You will have to do the 3.3 upgrade to the old emaxx as the stock old emaxx driveshafts or cvds will not fit the new diffs without modifications. The pin that holds the driveshafts on is closer to the case on the new emaxx. Same issue with the center driveshafts, easiest to use the revo style ones that come with the new emaxx.

The steering is better designed with very poor stock servos. And one good aftermarket servo will outperform the dual servos without the hassle of setting them up and stripping the gears.
As for the diffs, just trim the little ring on the stock driveshafts and it will bolt right up. I use a pair of nail clippers but a hobby knife would be easier. The 3905 diffs are an improvement over the 3906 pieces but a 3906 4 screw case with a cheap aluminum cup is stronger yet.
What I did with my truck is kept the stock chassis and upgraded the drivelines. I use 3905 driveshafts, Revo 3.3 center shafts 3905 axle carriers. I use a stock 3905 front diff and a spooled 3906 rear diff. This way I can keep the two speed transmission, single steering servo and symetrical motor plate. The 3905 chassis is known to break just as bad, maybe worse, than the 3906 chassis without significant handling improvement. The 3905 feels more stable not because of the longer chassis but because of the wider stance. The 3905 driveshafts, turnbuckles and axle carriers will add quite a bit of width to your 3906 making it much more stable through the turns and the 3906 set-up is lighter with better gearing for improved acceleration and less stress on parts due to weight.
