By the way, anyone know what could be causing erratic speedo readings if the actual gauge checks out?
My 91 has a mechanical speedometer off the driveshaft area. When someone was working on the parking break they miss - routed the flex shaft and put a bind in it. I disconnected the PB linkage, disconnected the shaft and put it back where it was supposed to be. Uncoupled the head end and forced some graphite lube down the shaft under pressure. It is working very smooth now. I would look for some binding if it is indeed mechanical. Good luck,
