Does anyone here know the size of the nut on the shift linkage cable that's used for adjustment? I've tried using pliers, but the handle's are always too long to rotate the nut once I do get a grip on it. All of my open-end wrenches are American and none fit, so I'm guessing that the nut is metric (probably 10mm like almost everything else, but I just wanted to check first). Also, does anyone have any suggestions on loosening this nut? Any ideas would really be appriciated! -Robert vin 6585
