Today I replaced the 4 main green lights in my 87 LE's cluster with blue LEDs, following instructions found in this thread:

It worked great. Nice blue LED lights now glowing BUT after driving it tonight I noticed that my speedo and my tach are now both off by a little. I did take the plastic lens cover off the cluster itself and I cleaned the cluster pretty good with a rag (I figured as long as I had it apart) I remember bumping the needles. Did I do something as simple as bump the needles out of correct position? It was VERY easy to take the dash apart and get down to the cluster itself. I had an easy time disconnecting everything on the back too. Both needles still move as they should as I speed up/slow down. Rats! As far as getting the speedo correct, is it going to take driving it with the lens off, GPS in hand, and moving the needle by hand to match up with the GPS? Am I even on the right track here?

Both worked perfect before. I hate it when I mess something up while I am trying to make something else better!
