I know the VSS changed in 93 for the gas trucks and the 2WD auto diesel trucks, but the clusters appear to be the same for the manual trans and 4WD trucks with just a single VSS signal wire to the speedo. Do they interchange and will the 91.5-92 speedos interchange as well? I'm looking for a speedo for the 93 RC cluster in my 74 crew.
