I suppose the bottom line is if you are restoring your car to bring you lasting fun for years to come, or if you are restoring you car to win national paint dot competitions at judged shows.
If your goal is to have a nice car for years to come, the aftermarket parts will be just fine. If your doing the judged national paint dot restoration competitions, you better start looking for a rust free 2 door version of the body you have.
What is your expected outcome? Gene
