Correct. The shafts should be same length but I got a bad one.
Actually all makes of diff are similar. I've own a kyosho MP7.5 before and it is the same design. As for leaking diff, It depends on how well you build it and make sure the contact space on the gasket is clean. What I used to do on my 1/10 MTX is use double gasket and a layer of silicon (Glass glue).
One thing about the Xray diff is it uses an 'o' ring on the back of the smaller gears (grooved). It use this config in the Front and center diff, and not the rear. This gives the diff a "stiffer" feel. I'm worry that when the o ring starts to aged, the diff will have different feel and need re-building a lot.
Well, we'll see...
Apart from the little pin, the kit was excellent, as always Xray.
