The back ones are a bit tough but all I can say is unhook them from the plug and you will need to lightly pull on them (there may be some hold downs that need to be removed) so that you can follow them and put them back where they came from. Below is a diagram of how they are routed,
I can not see the distributor or the back plugs con you show me a picture or a diagraom of the step by step way to do this
In order to change the rear plugs without the benifit of a lift, you will need to remove the upper intake manifold:
Upper intake manifold:
CAUTION Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure MUST be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
CAUTION Wrap shop towels around the connection to catch any gasoline spillage.
It may be helpful to identify and tag each sensor connector and vacuum connection as it is being removed or disengaged. This may save time at assembly.

The distributor cap is accessible by removing the air intake tube from the aircleaner to the throttle body:
