yes the old diff for the front fits. The new oneway is a one way/solid combo The geometry of the bulkheads and suspension arms did not change.
No blue this time. The reason all is silver is that the annodizing color causes variation in parts fit so to get a better more consistant fit the parts are straight alumunium.
The shock bladders did not change but the assembly instructions now indicate that you superglue the bladder to the top of the plastic eyelet. This keeps the bladder in place and is what the team does. IE the shock won't leak because the bladder fell in the tube. If you have a previous G4 do this and you will find the bladders work fine.
Notice you even get the reciever pack with the car this time. Rear belt tensioner is on the chassis
Just here to give the world grief.
