yes on the charger the internal parts will not inter change and the charger housing nose mount it different. if I remember ,,,it was a year ago that i did the charger stuff,, you can put the Challenger rear in , but have to change the mounting bolt placement ,,hubs brakes and axles. i am trying to make so there is little to no extra work for the swap.

if you have found something that we missed please let me know we are all in the learn mode. jim
