I have a job where I must install two new door panels into existing door frames. Not too difficult... However the frames are 1/2" or more out of square top to sides and the jambs are not plumb. I had convinced them that it would be easier to start over with new pre-hung doors but the cost did not settle well. I wonder if there is any "easy" way to fit the new panels to these parallelogram openings? Maybe make a fullsize template?
