Does this sound right? Also all I need is a gear,,, not the gear housing,,, that works as a cam setting correct? I appreacate any help.. also where can I get this gear? Thanks..

If the odometer is correct and the speedo is off, the problem is in the speedo head. The actual tire diameter is needed to compute the pinion needed, lots of sources for the pinions such as Brewers, e-bay, etc. The INTERNET, the MISinformation superhighway
