I put a set in my '94 a week ago- my tip: be careful not to drop the needles!! that sucks, trust me
once i was done, i thought i had the needles on perfect, but when i hooked everything back up, they were all a little off, so i had to do some fine tuning.
take a photo or draw a picture of where your needles are while the car is running before you take the needles off. once you get the gauges switched, you'll need to calibrate the needles while the car is running again. that seems to be the best (if not the only) way to get them accurate. this may not work for your speedo, though. that you might need to do on the road with a friend in another car or something... hope that helped!
