Repro Door Handles Causing Doors not to Unlock?

[cgrossl]

I just got through having my truck painted. I had my body man install new, reproduction door handles on the finished truck. If I puch the lock button down on the doors, then shut them, they will sometimes be impossible to unlock. You just can't pull the lock button up. To fix this condition, I have to wiggle the rod around that goes from the door handle to the door latch. Then the door will unlock fine. I compared the factory and the repro door handle and they are a little different. It looks like the linkage rod needs to be a little longer to work with the repro door handle. Is there any tricks to getting the repro door handles to work correctly?
