I have my grandfathers 51 gmc which was a one owner and has lots of memories as my grandfather and I spend a lot of time in that old truck. It was a 3/4 ton work truck and I am planning on restoring back to when I was a kid. It has a huge checker plate steel rear bumper with a big trailer ball mounted on the steel plate and had fender bliners and I want to make it as original as possible but more interested in taking it back to when I was a kid working on the 40 acres with my grandfather. So I will try to keep it 6v positive ground etc. Will that be a real probllem to keep it 6v positive ground?

I have just retired so I look forward to this project.

thanks
