Be very careful that your unibody is not tweaked before you weld in subframe connectors. US Cartool makes some great ones as do several others. You can even make your own.
Your doors are heavy, and the door hinges might need to be rebuilt, which you will want to do prior to adjusting your doors and/or putting in the sub-frame connectors.
You might even want to download the frame specs to your car and take it to a good frame shop to make sure everything is straight before you essencially freeze it in that position with subframe connectors.
Does the car have any rust, stress cracks or broken spot welds?
