Thank you, excellent
Thank you, excellent suggestion. And now that you mention the strikers, I see plenty of doors that are in dire need of striker plate adjustment.
The striker plates on 308 series cars especially seem prone to coming loose or falling out of adjustment. Left unattended this malady tends to wear out the door lock itself. So when the doors become diffult when closing or hang up when opening it's time to pay attention to the hinge pins and the striker plates before the problem gets worse. When properly aligned and adjusted the doors should close rather smoothly and tightly against the weather seal. When they fail to do so it's really not that difficult to readjust the striker for a nice fit. After carefully loosening the 4 striker plate bolts (the heads round out easily so be very careful or simply use an impact hammer with proper socket) then snugging them back up and eyeing the mechanisms while carefully closing & opening the door fine adjustments can be made to the striker to achieve nice alignment with the lock, once satisfied the alignment is as good as it can get re-tighten the holding fastners to secure everything in position. However if the hinge pins are worn out this nice alignment may not be possible, more on hinge pins later.
