The +/- 68 length is for the 4 speed? Sounds better as it may give me a few extra inches to effect a smoother bend...seems to work fine for 1000 miles then the speedo starts jumping then it snaps....frustrating....wondering if the copies are crap as well....

What would be the purpose of a 2 piece unless you had cruise control? Not sure there but I do see them as well in the catalogue, which is unclear (CI's anyhow)
