I'm pretty sure the Temp sender is different as when I asked about this cause I'm doin a V6 to V8 swap I was told to get a V8 panel as the Temp and Tacho were different. Sometimes you can buy them on Ebay pretty cheap or if you have your old 1 just swap the Tacho and Temp gauges with the new 1. It's not all that hard to do, or if you just want the 250Kmh speedo just put the speedo in your old 1.
