About a week and half ago, someone ran a red light and totalled my '99 GTP. I have a '98 GT with about 140,000 miles that I was thinking about transplanting the GTP engine and trans into. Would it need the computer or wiring harness switched over as well? The GTP has no leaks and about 108,000 miles. The '98 leaks a little oil, but nothing major. I just don't know if it would be worth it money wise to do the swap. I would have to pay someone to do the work.
