Thanks itoldyouso, I had seen those runtz reducers and wondered. I hear from the speedo repair guys it does matter about the positive ground. They are telling me it will ruin the gauge if I do it this way, wonder if they just want the business. I just want some cool old gauges, and dont want to spend tons of cash to get it working. I was hoping someone else had done it successfully? If I dont get any other replys, I'll let you all know what happens after these voltage reducers show up. I just might have a nice looking set of gauges for sale!!
