My '92 which my dad is using while in town has the 5 speed manual tranny with granny gear and 350. The clutch was replaced at the shop a few months ago and the clutch pedal is REAL hard to press down. Shop said it should loosen up as it "wears in". Well, it hasn't and is becoming a real PITA to drive. Is there anything we can do to adjust it, or is there an installation problem? The truck only has 98K miles.
