I purchased them over 10 years ago from a company called Chevy Duty. Soon after I purchased them, I moved and the project was put on hold. I have since moved two more times, but I'm finally getting some free time on weekends to start working on my truck again. Unfortunately I disregarded the old rusted side panels during all the moving around the country.
I'm basically looking for a template or instructions on how to cut the holes in these panels (since Chevy Duty no longer exists). I think they changed to Classic Parts, but they do not have anything that will help.
