Latch & Striker Installation

Install striker bolt in door frame.
Close door carefully and check for interference between head of striker bolt and latch components.
Add or remove shims under striker bolt washer as required (outside diameter of shim should be larger than outside diameter of striker bolt washer).
Adjust striker bolt vertically so door is not guided upward or downward while being closed
CHECK TO DETERMINE THAT BOTH SECONDARY AND PRIMARY LATCHING POSITIONS ARE USABLE.
Door should be latched but not "closed" in secondary position and latched to anticipated "closed" position with respect to adjacent surfaces in primary position.
If both primary and secondary positions are not evident, readjust striker bolt.
After installation, check door alignment and door seal pressures

Caution: Latch does not meet FMVSS 206 (ECE R11) load requirements.
