My chassis twisted hardcore Options

[turnaround89]

I braced the chassis, but obviously not enough. I lined the doors up properly, had the gaps correct, and then put the braces in. I took the braces out today, and went to test fit the passenger door and it won't even come close to shutting. the door lock does not line up, i tried adjusting the hinges but had no luck. The things are way off....any one have a fix? I really don't want to buy a tub because i just put a ton of work into this one. If it comes down to buying a tub, i guess thats what ill have to do, but i really would like to avoid that.

update: the drivers side door fits properly, shimmed the bottom and it works the way it should. All i have to worry about now is getting the passenger side door to shut and the targa top to fit correctly. I know the problem with the targa top is the the car actually rotated on an axis slightly. The top latches securely with three latches, but the passenger side one won't line up. You can also see the top overhangs the rollbar on the passenger side and doesn't line up there. My question is should i start with the targa top first and get that to fit correctly or work on the door? Either way i have to cut out some metal, just wondering if one should be done before the other.

My plan to get the targa top to fit would be to push under the corner of the car and rotate the car back the other direction. Cut the car almost in half(leave the center tunnel alone and intact), but the floor pans and longs would be cut. Then with a bottle jack, jack up the opposite side of the car(drivers side) rotating the chassis back into alignment. Measuring along the way from rollbar to door hinge plate, so things line up.

For the door, it would be similar but jacking the car apart parallel to the door opening itself. Since the door hangs down, at the back, having the car twisted back into alignment should fix, if not repair, that problem. I know the door opening has to be pushed further apart because the triangular window hits the windshield frame. This is where jacking the car apart in the door opening comes in, jack the car apart, somehow hold that spacing and place the door back on and make sure everything lines up.

I am open to any comments anyone has to modify my methods. I thought i would start this next week, but i have spring break from the 8th thru the 12th, plenty of time then to work on this.

Let me try to break this down for you if I can. Porsche doors don't get shims. If the door required shims on the lower hinge the car is bent.

Here's a crude drawing of what you should try based on your discription.



Get a hand pump port-o-power and carefully set it up in the car. The lower should be on top of the long in the corner against the rear bulkhead. The other end should be against a wood block about the height of the upper hinge. Take a mm tape measure and check your progress.
