Speedometer Problems

Just bought a 2000 5 speed TRD Tacoma, all is well except for the speedometer. When stationary it shows 0 mph as it should. But as soon as you start moving it shows about 45 mph. In all the maintenance records I got from the previous owner this is a handwritten quote on a receipt that was from a diagnosis. Although there are no part numbers it lists a dash unit for $300. Does anybody know what this is, or if this is even the problem? Also, this is the plainest instrument cluster ever as it's missing a tach. Is it possible to put a cluster with one in its place?

 

as far as the speedometer being off i had the same problem when i knocked of the black peg off that sets the needle at 0 so to fix it i had to rotate it clockwise all the way around back to 0 again and that fixed mine

 

I would understand what to do if the case was just the needle pointing in the wrong direction. But regardless of what speed I'm doing it shows 45 mph, except when stationary.
