Right on Spicer! I used the GM alternator, ran one wire to the original starter switch to get juice back to the battery, diconnected the 100 amp charging system and cables, then removed them from the truck. I also had to run a new power wire to the ignition switch. I used a mini hi torque starter and life has been good! I also had to change all the bulbs, I wish somebody knew if we could run 12 volt sending units on the stock instruments.
