Mk1 door alignment

So it looks like something's moved over the last 12 months since the doors were last fitted.
Perhaps the welding of the roll cage front feet has distorted the lower? A pillar and door hinges.
Both doors bolt up fine and easily and swing freely. However closing both against the body and its obvious there is a problem. probably 20mm sag to the rear.
the doors will engage with the strike plate with a big push, momentum bending whatever to allow them to close, the alignment then is fine, body creases match and the gaps aren't too bad (bit tight on passenger rear) but opening them is now very, very difficult.
What alignment techniques are available to me before I cut and shut one or both hinges?
I have tried levering the door, and managed to lift the shell off its supports, ive tried a jack and block of wood under the door.
I've currently removed both lower hinge pin bolts and the door closes fine with about 3-5mm displacement to lower hinge.
my last resort action is to cut the lower hinge, align door all around then refix the hinge and pray!
Please help.
