I bought my '70 Duster 340 last November and immediately started looking things over. Had a lot of little electrical gremlins. The under dash wiring harness was in poor shape and had been hacked up, so I ended up getting a new repop. While the instrument cluster was out, I also replaced the two circuit boards in the rallye dash because some of the pins were bad. Lots of work, but all is happy now. The wiring in those old harnesses get brittle, corroded by moisture from leaks, and people hacking. Was so nice to be able to plug in fresh connectors and have everything work again!
