On my conv sedan I have similar problem, I figured it was the cowl post --the side holes are out of position by the amount needed to get door alignment, my body was cross braced and door braced, but looking at how the body fits on the frame there is a larger gap between the floor and the floor pan each side of the door hinge post ----on my car the inside bottom of the cowl post was made too long, pushes the floor down

shimming the front of the cowl a lot can make it harder to get hood/fender /grille alignment

was the frame checked /straightened

compare measurements on each side---top of floor to factory holes/seams on cowl, top attachments,door striker holes etc at rear to the floor on each side ----

before paint the whole body, fenders,grill,hood need to be fitted

you have to lower the center or raise the ends, since you had work in the center start looking there for the problem
