Sticky speedo

[Mark's 68 L78 RS SS]

Hi guys:

My speedo is sticking and not reading the right speed.  Any special tricks to replacing the cable?  I see there are several lengths available so I will need to research which one is correct for a 68 L78 with M22.

Thanks in advance for any advice.

Are you sure you just don't need to lubricate the speedo cable.  A year or so ago, the speedometer on my 68 buzzed and jumped around.  A little lubrication and it's worked fine since.  Your local parts store should have the lubricant (It's got graphite in it... although some folks swear by white grease and a low viscosity oil combination.)  The point is you will have the cable out as it is, so if it looks dry, try the cheap fix first.

You make a good point and we already lubed it once.  i will check to make sure we did it good but I am thinking I will just replace it.  They are not too expensive and it will just eliminate the problem.
