^^Like he said, go to a good body shop. The cost will depend on if you need it painted or not. Usually a Body Shop has a labor rate of around $35-40 an hour. I'm not sure how many hours of labor it is to install a JDM Conversion...but you're probably looking at around $150-$200 (just estimating) <----and if you need it painted...you can double that price and add some.
