well i currently am working on a 1980 280ZX 2+2 and undergoing a turbo motor swap. ive aquired a 83 motor, 83 ECU and wire harness, and was looking to update my gauges. now i was hoping to go for the 130mph needle cluster, but it recently has been brought to my attention that the 130mph gauges were only available in the 1979 models (did not know that before). so i was wondering would it be worth getting the 130mph cluster, and would it actually work on a newer setup? would appreciate some help, comments, or maybe even a how to convert if one exist.
