Ok thanks, I'll replace both sides then, any idea on that centre wheel on the drive shaft? Tried to load pictures off my phone but it wouldn't let. Me

So with the manual to reference made the old track removal a cinch, only ran into a few problems with some parts condition, thebearing for my drive shaft on the clutch side is completely toast, not sure if there are after market one available today? And my Drive shaft centre wheel is pretty bent but...

New to this site and went through the FAQs, and that other then buying the manual is there any other info I can use to help me with a track replacement on my 1976 liquifire 340
