"Parts guy explained a 6 volt will help the points last longer."
Parts guy was BADLY misinformed! A 6-Volt coil used in an ignition system WITHOUT having a resistor to compensate for it will KILL the breaker points.
The 2010 had a resistor on the back of the ignition switch, or some had/were changed over to a length of resistance wire, making it OK to use a 6-Volt coil.
(Note the starting bypass connection in the drawing.)
The advantage to using a 6-Volt coil AND a resistor in the primary circuit is that the resistor can be bypassed (by a connection to a special post on the starter solenoid) during cranking to make for a "hotter" spark by compensating for the dropped battery voltage that occurs during cranking.
On the other hand, if NOT using a resistor in the primary circuit you MUST use a "true" 12 Volt coil designed with more primary windings to allow use on 12 Volts without drawing excessive current that leads to burned points and/or coil failure from excessive heat.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
