I came a across a terrific deal on a GM dual mass flywheel. I decided to use it to replace a damaged solid mass flywheel. This is in a 1998 K3500 truck 6.5D, with 5 speed,internal clutch slave. Here's the problem... The dual mass flywheel is about 1/2in. thicker than the solid mass flywheel, as a result it moved the entire clutch assembly back, causing the internal slave to constantly engage the clutch (open it) and being as the internal slave is fixed in dimension (not adjustable), I have a problem getting my truck to move... any ideas?
