Hello,
Ok when I got my car a couple years ago it had a caved in front fender headlight and the car had been sitting wrecked for so long that a hail storm came through and pretty much screwed the rest of the car. Needless to say about every pannel on my car has been replaced. I did it all myself with the help of ebay and ups. I shipped fenders a hood, a door, targa, rear hatch and a spoiler. so it can be done. As far a adjusting I took my time and had another person to help push hold ect. The hood and fenders and headlight gaps are all adjustable it just takes lots of adjusting. My sugestion is to pull off the hood, inner fenders,fenders, front clip, headlights ect and look at all of the brackets and see what needs to be straightened or replaced. I personally would do all the body work on the pulled parts while they are off but thats up to you. After everything is done and everything looks good get a buddy and line shit up. None of it is hard everything comes off real easy there are some hidden bolts/ nuts on fenders. I would get yourself a manual it should have all info you need as far as how to remove parts ect. Or shoot me a email I am happy to help. With a Supra you need to be able to do it yourself or you will get poor real fast.
