Known issues on the 1983 C70. No recall was ever issued for the 1983 C70, and no owner has filed a complaint, so the federal record is clean. What the manual documents instead is a heavily configurable truck: seven engines with their own specifications and torque values, two body types on three chassis codes, and the transmission, driveline, axle, brake, steering and electrical procedures that hold good for whichever combination came off the line.
