So, installed a new angle drive to fix my original that was leaking. Went for a drive out to the desert, doing the "Pines to Palms" highway, and on the way there my speedo stopped working. Also meaning my odometer stopped working too, which I use to gauge when its time to fuel.
Huh.
Well, no biggy, I can drive without a speedo. I drove another 140 miles and arrived in Thermal, CA.
So I removed the angle drive and spun the cable, and the speedo jumped. So, the cable isn't broken.
