Door latch adjustment help needed Options

[airsix]

My passenger door outside latch has been non-op since I bought the car. I dug into it yesterday to get it back in service. I sucessfully repaired the damaged fork on the flapper handle. The latch mechanism in the door functions properly now. The problem is that when the door is closed, the force required to open is so high the latch is going to fail again if used in this condition. If I apply some pressure against the outside of the door the latch can be opened with the correct amount of effort. So, I thought the striker in the door-jam just needed to be adjusted out a little. Probelm is that it's already at the end of it's travel.

Any ideas? I don't know if this is something else to adjust that I'm not seeing, or what. I'll keep at it, but thought I'd check with you guys in the mean time. I've got autocross school next week and need the passenger door to work. Thanks much.
