speedometer stopped working

My car sat on a Sheriffs impound lot for a couple of years in Texas before I bought it. When I got it, the speedometer needle would jump at speeds up to about 50 or so then over that would smooth out and read steady. After a while it started doing what it continues to do which is at about 25 it reads way high, maybe 60MPH and is pegged out by about 30 or 40 MPH actual speed, therefore, without the tach I have no idea of my speed as it shows 85+ MPH at anything over 30 or 40.
I am wary to tear into it without having a suggestion from some who might have run into this before. It seemed to act like the needle (speedometer head) needed to be lubed before it started pegging out at low speeds but there aren't many (soobs w/ good speedometers) left in the yards around here so didn't want to entirely ruin what I had by ripping it apart to troubleshoot if I could find a possible solution to prevent troubleshooting and experimentation.
Any ideas? :-\

first post, you just gotta reach up behind the speedo, and shove the cable back in. if you lay in the floorboard and look up, you should see a cable hanging down, that pushes up into the back of the speedo, easy fix

The cable is new. Has been replaced without effect on the speedometer issue.
The speedometer pegs out past 85 MPH by the time the car is travelling 40 MPH or so. That would indicate to me that the head or needle/indicator movement is dry, sticking, or other issue that causes it to turn close to 1:1 with the cable which it shouldn't do since it is turned indirectly by the cable using a magnetic field rather than cable directly turning the speedometer needle. I haven't had it apart, yet, so am no expert, but have had speedometers apart from other vehicles and am familiar with their operation...just would like input so I don't have to go into it blind (since I don't have a replacement should something come apart that is irrepairable).
Any other ideas? Any and all input accepted and appreciated.

The speedo head is dry (no oil drips) at the cable input.
I checked out the same type Q&A on the 'New Gen' section and it appeared to matter whether it was an AT or MT. I have the 5 speed D/R tranny. Will that matter in the seal leak issue?
