This is a very involved repair. The distributor is located on the front of the motor between the waterpump and the harmonic balancer. the Waterpump ,and anything else in the way will have to be removed.

Tips for a great answer:
Trace the spark plug wires to the distributor; it will be at the back of the engine block, in a cramped space.
Disconnect the negative battery cable to the distributor and unhook the air cleaner tube. Unscrew or unhook the clamps holding the distributor cap in place, and unscrew the Camshaft Position (CMP) sensor connector with a screwdriver.
Matchmark the distributor housing and the rotor for later realignment, as well as the distributor housing and the intake manifold. Unbolt the holding clamp and remove the distributor.
Set the engine at Top Dead Center (TDC) mark of the No. 1 cylinder compression stroke with a socket with breaker bar (long-handled ratchet).
Install the Ram distributor, replace the clamp and lightly tighten the bolt. The distributor part number is A1303801 from Parts Train, but numbers differ from different manufacturers. Order using the model, year and engine size.
Turn the distributor in its seating so the rotor lines up with the No. 1 cylinder mark on the Camshaft Position (CMP) sensor. Bolt the clamp bolt to 200 foot pounds (22.5 Nm).
Reattach the CMP sensor connector and use the screws or clamps to replace the distributor cap. Connect the air cleaner tube and the negative battery cable
