Okay, so i've got some problems... My 98 SVT, when disengaging the clutch in any gear, shakes/shudders. I've got 161k on the clock and I think it may be the original clutch. Also, when I slightly depress the clutch (1/2 Inch) while cruising in gear, it vibrates then also. Could this be a roll-resistor, or any other mounts, the clutch, etc..? I'm new to clutch issues, but am a very capable diy-er. Please help, as i've searched and have found no help at all. Thanks in adv.
