Ok so I'm down to just a couple annoying issues before I take this thing for body work and paint. The speedometer isn't fluid in movement. It jerks forward, then it will actually start backwards for a second. I know it isn't accurate. I have replaced the cable. I replaced the gauge. In the transmission I pulled out the gear but the teeth seem fine. I haven't altered the gear ratios. Apparently it is tough to find the parts that drive the speed? Any ideas?
