I will add a little info to this thread from my experience with clusters from my trucks.
First, the mileage can easily be turned back with a small screwdriver, 1 number at at time on the reel.
The issue of nonworking trip odo is usually the coupler between the odo and trip odo, the coupler can be glued back together easily.
I have a 95 tahoe with 350 tbi and swapped a cluster from a 96 truck 4.3 into it, everything worked except the tach read wrong. I assumed it was the difference between 6 and 8 cyl tach driver resistor boards. I did not modify it, but am pretty sure it would work. There is a thread on thirdgen.org dealing with repairing tach driver boards that is very informative. I had to do this for my 91 camaro. The resistor circuits look identical between the camaro and truck, but I did not test them. It basicly involves cutting 2 leads on the resistor circuit and soldering a pot or resistor across them. I first soldered a pot in and hooked up to a scanner to set it to the correct reading, then inhooked the pot and measured its resistance. Then solder resistors of the correct amount in its place. Y ou can also leave the pot installed and just put it behind the cluster. I am sure this would work with a little experimentation.
Also, the 95 and 96 cluster have different part numbers, but most of the components are the same and both of mine had a 95 manufacture date.
I will locate and post a link to the thirdgen tach info thread when I get a chance.
