Speedometer Problems
I have a '92 K1500 with aprox. 230,000miles the truck is in good condition except the speedometer doesnt work it hasnt for about 2yrs it has a manual trans I have already replaced the VSS on the tail of the trans with no effect I also tried changing out the gauge cluster with one from an identical truck also with no effect. I think there might be some kind of module between the sensor and the gauge. Please help thanks.

You are correct. There is a calibation unit behind the glovebox, it maybe burned up, here this may help:
