I'll say this, I heard so much good about the goodmark quarters and I'm not impressed. If I could do it over I would have went with the patch style. They are pretty straight, but still have creases from the stamping. They are thinner than original. Then you use other repop parts like extensions/wheelhouses and they dont come close to matching. Yes, best out there, but far from perfect. If I would have read info from people who used the panels, like someone thats an experience body man, I may have went a different route. So my point is, second hand knowledge is no better than a guess.
