I have used patch panels from americanclassics and lmc. Both are good and some fitting is always required. For $1500 I would do the work myself. I bought metal tools a Mig and gas, for practice I started on the tailgate I new I would not be using in the end. I worked up the the floor pan rockers and lower front door pockets and lower door skins. Read the post and tech tips on metal work and welding and do this yourself you will be more satisfied in the end.
