for the front guards, buy some off someone for cheap and practice on them before doin the proper job, but for the rear quaters the trusty basball bat might be the way to go before u go hacking with a grinder, cause theres nothing bog cant fix but welding a new panel on is a pretty big job lol, and finding a rear quater would be even harder, OR take it to a shop and pay them to do it, cause once u cut the outter panel off to shape, u will still need weld up the gap that will be left between the inner and the outter panel or water will get in there and then it will rust. even if u can get a shell that someone is giving away to practice grinding and welding on just so u know wats it gunna look like after u cut the outter skin off, and so u dont cut to high with the grinder and find urself with ur flairs sitting to high,
