First off Just 2 Suggestions,
If you have Aftermarket hinges?
That could be part of the issue.
Also, if you have replaced the rocker panels?
The rocker panels need to be fit to the doors.
Not the doors fit to the rocker panels.
Here is a place in Santa Ana.
This came up in a Quick search.
California Classics Paint & Body
1650 E Edinger Ave, Santa Ana, CA 92705
And here are a few threads that discuss this.
In case you decide to give it another try.
These may help you see an issue that was overlooked.
Hope this helps
