I totally agree with Carl that the repro door hinges are a major part of your door mounting issues. My personal research established that the door leafs are not formed to the proper bend and twist.
Finding and rebuilding an original set of door hinges will vastly improve the installation leaving only minor tweaking. I learned the hard way that repro door hinges and brake drums should be avoided at all costs. Research door fitment in the forums and you will find a lot of useful knowledge on how to master door fitment.
