i live in the baltimore area and i want to replace the entire floor , and both right and left rocker panels on my 69 camaro. my question is what can i expect to pay to have the old material cut out and the new parts welded in?

 

probably about 8 hours labor plus parts ( you can check the price of the parts at NPD or year one ) plus the repaint on your rockers. Of course, you're going to add hours if they have to pull the interior.
