I need to replace both of my inner fenders, and a wheel well. Instead of replacing them with the same parts, I was thinking about getting rid of everything from the firewall out and doing a tubed front end like some people here have. I have access to a tube bender, notcher, and mig welder, so I have all the tools I need. I'm pretty sure the tube will be cheaper than the replacement panels, but what are the plusses and minuses of doing this other than cost?
