New type bolts are installed in production from the following engine numbers:
43 H 11261-924S, 944 Manual trans. 43 H 62894-924S, 944 Auto trans. 42 H 05462-944S 45 H 03874-944 Turbo
IMPORTANT
Because the new bolts are longer, the drive gear bolt holes are drilled and tapped completely through. This means the new type bolts cannot be installed in old style drive gears.
Former version hex bolts, M6 x 16 with a torque of 8 N-m (6 ft.lbs.), are still available for repairs to earlier vehicles.
