Classic/Antique Car Repair: 1964 dodge dart, rotor position, dodge dart

Question
I am tuning up a 1964 dodge dart with a 3.7L slant 6.  I'm having trouble ordering the cap and rotor. Rock auto is saying that there is three options for the car and rotor.  They say there is either a chrysler distributor or two options for a prestolite distributor. Which one do I have?

Answer
The make of the distributor and the part number is printed on the side of the distributor. You might be able to see it with a mirror, if not you will need to remove the distributor. On these cars i always found it easier to install and adjust the points with the distributor out of the car. Just mark the rotor position before removing the unit for re installation and do not turn the engine over while the distributor is out of the car.
