Anybody know where I can have the original instrument assembly rebuilt? My tachometer keep sticking and reading incorrectly as a result and I think my oil pressure gauge is starting to go bad since it will all of a sudden shoot to the left and then reset itself. Also, somehow my fuel gauge has started to read differently. When the needle is at the last 1/4 mark, it has almost 10 gallons left. I need to find a new cluster, or have this one rebuilt. New clusters are expensive and hard to come by so I'd prefer rebuilt.
