Thanks for the replies so far. I actually just bought this yesterday. I was in the process of overhauling a different 70, but I picked this one up on an estate sale for cheap. I had the tractor trailered home part way and I drove it home the remaining 15 miles. It's been repainted at one time and is missing the decals, which I ordered today. It's not museum quality, but it's tractor show/parade quality, my reason for replacing the gauges. The 15 miles was in about 90 degree weather and it had some hard carbon getting blown out of the exhaust the final 5 miles, so it probably hasn't been worked hard for quite a few years.
