If your really dead set on repairing that car (which I still advise that you don't bother), you should be able to get any parts you need from a salvage yard. Another option is to buy a cheap donor car, remove what you need, and then either sell the rest of the donor car to a salvage yard or part it out yourself and try to recoup your money.
