I hooked up my speedometer cable after the rebuild and made sure there weren't any bad bends and it was seated properly but at first it only read about 33 MPH when I was doing about 70 MPH. I wiggled it a little bit (the cable that is) and now it just spins around in complete circles. The faster I go, the faster it goes. While I like the psycadelic spiral effect i'm getting i'm worried about the speeding ticket effect I might get. Anyone have a remedy. 85 Blazer on an 82 chassis, 6.2L Diesel, ORD flip, 35's with no cutting on a 4" lift.
