How the hell do you align doors

Building my 61 Beetle and want advise on aligning the doors. I cant see how sliding a hinge in or out at the front will alter the back edge of the door when in the closed position (hope that makes sense). In other words to get a square edge between door and 'B' pillar.

Do you actually have to heat and bend the 1/4 inch plates of the hinge itself.

I understand the door striker sets the height at the rear of the door so the body crease lines up. But is the door meant to lift a 1/4 inch + at the rear when it sits into the striker. The door drops when you actually open it, is this normal.

I'm stuffed if I can work it out. Any help would be appreciated.

Thanks, Kevin

Something is bent and will need to be straightened.. The door should have 'even' gaps to the body all around it and teh door should 'swing' nicely on its hinges; the striker plate shouldn't be doing much 'work'. The hinges do get bent when doors are opened too far - usually when they fly open around corners; the A pillars flex and bend too

is there wear in the hinge pins ?

Can you move the door up and down when its open ?

Thanks VWCOOL and I have just had 4 oversized pins fitted at Vintage Veedubs.
