Ok, the bed level did so good let me ask another question. As I said I'm mocking the truck together since I bought it all apart. I have the core support and the inner fenders installed and then tried to put on the outer fender. Problem, had to loosen the inner fender up to gain clearance under the core support to get it on. It didn't seem like this was the correct order to do this install. I'll never get a fresh painted fender to go on without some damage to the paint. So, what is the most correct way to do this. I suspect add the core support last after the inner and outer are in place. Thanks in advance for advice. How do I post pics of my project?
