Speedometers buggerd11

my speddo in my f100 is not working wat could the reason be like i filled it up with peddy and the gauge went to half way but never went down and is all buggerd would it be the cable or the speedo itself and if its the speedo would i have to buy the same year and model speedo or just any speedo?

I would suggest stopping by a local speedometer shop and see what they want to fix it. Generally they are less expensive that you would expect.

Just for the record I can’t see how a cable problem would cause the problems you report.
