As Bill mentions the fit and finish was never 100% and add to that the 'trauma' the truck may have experienced in over 50 years use.
I spent a long time working my door hinges to achieve an acceptable fit.i.e. filing out bolt holes etc.
And even then they're not 100% perfect,but a dang sight better than they were.
Most importantly,be patient....
Admitedly mine's an AD but the principles are the same regardless.
Once you're happy with the fit,drill an 1/8" hole through the hinge plate into the the pillar,that way if you remove the doors for paint/bodywork,you can then re-fit using the 1/8" hole for alignment.(A tip I got here at the 'bolt)
Good luck.
