All Fords in the v8 years from 32 through 55 I believe, were 6v positive ground systems (as were a lot of other car of that time period). When Ford switched to a 12v system in 56, they also switched to negative ground.

6v vs 12v to quote Alice in Wonderland, to know which way you need to go you need to first decide where you want to end up. If you are wanting to keep the truck original stick with the 6v, it will work fine. If you are modifying it and adding stereo equipment, gps, or whatever, you might considering switching it to 12v.
