I disagree there...the Dynacorn quarters fit almost perfectly...very little fooling with them...and this was on a coupe, which is known to have fitment issues with the driver-side repro panels. It fit perfectly to the filler panel, the door jamb, and the taillight panel, I had trouble with the new outer wheelhousings. The inner wheelhousings and quarters were Dynacorn, but had to use some other repro outer wheelhousings and I had to slice them a bit for proper fitment. I think if using Dynacorn quarters you will spend more time patching in a piece and doing bodywork than if you replaced them outright....of course there are other issues with aftermarket quarters, such as the body lines not being as crisp, but that is another issue entirely(or maybe its not?)I definitely would not replace the entire quarter. Nothing fits up against the existing panels like the original panels. No fighting a poorly fitting panel, you just cut you quarter to fit the space you need.
