you won't have to move anything if you get '71 or '72 axles, if you get '73 or newer, you will have to move perches and shock mounts, you can take the rear axle/housing assembly to a shop and they can move these for you, they would be at the stock angle, you can add angled wedges later to tilt your pumpkin upward if you need to....hope this helps...
