speedometer off

[btolds]

I just bought a 74 firebird w/turbo 350 trans . The speedometer is off so I replace the it with a new one but it still off @35 mphs its show 55 mphs. I don't if tires, rims, or gear have been change. I heard I could replace the plastic speedometer output drive in the transmission. If so what size to get the any other help or ideals would be great.

I think this site will help you answer some questions:

Basically you have to match up the speedo gear with your ring and pinion gears.
